The mechanic did no work but returned the airplane to service with an endorsement that the annual inspection/airworthiness requirements had been met based on his determination that the engine runup was satisfactory. The airplane departed but returned to the airport shortly after the departure. During the return, a witness said that the airplane was "way too high," and its approach was "pretty steep." The airplane touched down about halfway down the short-grass runway and was "going way too fast." The airplane overran the end of the runway and into a pond where it became submerged. Postaccident examination of the runway revealed the presence of skid marks from the airplane main landing gear wheels along the last 300 ft of the runway. The propeller exhibited rotational signatures but with some loss of torque. Postaccident examination of the airplane revealed numerous unairworthy maintenance items and/or lack of maintenance to the engine and accessories; further the engine and various accessories surpassed their manufacturers' recommended time for overhaul/replacement. The exhaust manifold was blocked with internal fractured pieces that would have resulted in power loss. The condition of these pieces was consistent with a failure that had been preexisting. The induction hose to the carburetor was the wrong part for the installation. The hose was collapsed and would have restricted airflow into the carburetor resulting in power loss. Both magnetos were no longer serviceable and would have produced minimal ignition. The engine timing was not set to the engine manufacturer's specification. Had the mechanic conducted a proper annual inspection, he would have identified many of the issues found during the airplane's postaccident examination. Based on the evidence, the pilot likely returned to the airport due to a loss of engine power. It could not be determined which of the many discrepancies led to the loss of engine power. Further, the pilot did not attain a power-off approach glideslope that would have led to a proper touchdown point near the approach end of the runway. ## Factual narrative FAA safety publication, On Landings Part II, FAA-P-8740-12 (2008), Runway Surface, stated: Runway surface make a big difference on landing long because it plays a big role in braking. A dry, concrete runway offers one of the best braking surfaces, a runway covered with wet, clear ice offers the worst braking surface. Most other conditions fall somewhere between the two. Grass is a much less effective braking surface. Wet or frost-covered grass is even worse. The 1971-model-year Piper PA-28-140 (Cherokee) airplane was purchased by the pilot and his brother on November 3, 2010, and the aircraft registration was accepted on February 9, 2011 The airplane was powered by a Lycoming O-320-E3D, serial number L-46554-27A, case number 4865, engine that underwent its last overhaul by the engine manufacturer dated June 29, 1988, at an engine total time of 1,945.45 hours. The engine underwent its last overhaul, which was performed by an airframe and power plant mechanic, dated May 29, 1998, at an engine total time of 2,991.8 hours and a tachometer time of 4,236.2 hours. The Hobbs meter and tachometer indications at the accident site were 889.5 hours and 5,063.7 hours, respectively. According to an airframe and powerplant mechanic, the pilot called him at the end of February 2017 to schedule an annual inspection of the airplane. The pilot did not report any issues and said that the airplane had been flying "beautifully." On the day of the inspection, March 4, 2017, the mechanic arrived and the airplane was at 30TX and the airplane was already "opened up." The pilot reported that the airplane was having occasional fuel pressure problems. Upon completion of the inspection, the airplane was towed outside, started easily, and the engine was run for about 10 minutes. The mechanic stated that the engine was running "satisfactorily," and he signed off the logbooks. According to an FAA inspector from the SAT FSDO, the mechanic, who signed off the annual inspection, stated that he watched but did not work on the airplane. The mechanic and the pilot used an inspection checklist that was not the inspection checklist in the Piper Cherokee Service Manual. It is unknown if the mechanic or the pilot used the Piper Cherokee Service Manual during the inspection of the airplane. Since 2011, all of the annual inspections, which were performed every year, were signed by the mechanic that had signed off the annual inspection. Lycoming Service Instruction No. 1009AZ stated, in part: Engine deterioration in the form of corrosion (rust) and the drying out and hardening of composition materials such as gaskets, seals, flexible hoses and fuel pump diaphragms can occur if an engine is out of service for an extended period of time. Due to the loss of a protective oil film after an extended period of inactivity, abnormal wear on soft metal bearing surfaces can occur during engine start. Therefore, all engines that do not accumulate the hourly period of TBO specified in this publicationare recommended to be overhauled in the twelfth year. A review of the engine and airframe logbooks revealed that the magnetos, exhaust, fuel and oil lines, and carburetor had not been replaced/overhauled since the engine's last overhaul in 1998. The Piper Cherokee Service Manual states that a 100-hour inspection is a complete inspection of the airplane, identical to an annual inspection. The manual stated to replace the engine flexible hoses (fuel, oil, etc.) as required but not to exceed 1,000 hours time-in-service, 8 years, or engine overhaul, whichever comes first; no fluid hose may exceed 20 years time-in-service. The Airplane Flight Manual (AFM) provided landing distance versus density altitude information for the only the following conditions: flaps 40°; power off; paved, level runway; no wind; maximum braking; short field effort; and airplane gross weight of 2,150 lbs. Based upon a density altitude of 1,535 ft, the landing distance at gross weight was about 550 ft, and the landing distance over a 50-ft obstacle was about 1,100 ft. On March 25, 2017, about 1530 central daylight time, a Piper PA-28-140, N4329T, impacted a fence and pond during a landing overrun on runway 18 at Burg Lake Aero Airport (30TX), Stonewall, Texas. The commercial pilot received fatal injuries, and the airplane sustained substantial damage. The airplane was owned by the pilot and his brother and operated by the pilot under Title 14 Code of Federal Regulations (CFR) Part 91 as a personal flight. Day visual meteorological conditions prevailed at the time of the accident and no flight plan had been filed. The flight originated from 30TX about 1525 and was destined to New Braunfels Regional Airport (BAZ), New Braunfels, Texas, but returned to 30TX. The accident flight was the airplane's first flight after its annual inspection and the replacement of one of the fuel pumps. The pilot's brother-in-law stated that the pilot performed a full-power run-up, which was "okay.". The airplane engine cowl was then put back onto the airplane, and the pilot fueled the airplane from the airport fuel tank to a level that was at the fuel tank "tabs." The pilot then performed another engine run-up at full power near the approach end of the runway 18. During the takeoff, the airplane was not more than 10 ft above the runway when it was at about half down the length of the runway. The brother-in-law thought the airplane was going to hit trees located near the departure end of the runway. The airplane had been gone for about 5-10 minutes before it returned to airport. The brother-in-law reported that the airplane touched down about halfway down the runway, and it was "going way too fast." He thought that the pilot never increased engine power after the airplane touched down and that the engine power was at idle during the landing but was "not sure" because he was in his hangar, and the airplane does not produce much engine noise at idle. A witness who was driving westbound towardStonewall, Texas, saw an airplane descend toward the 30TX runway. He said the airplane was "way too high," and its approach was "pretty steep." He said that he thought to himself that the airplane was "not going to make it." He stated that he was in his truck with the windows closed and could not hear the airplane engine. The airplane overran the departure end of the runway during the landing, went through a barbed wire fence, and into a pond. Central Texas Autopsy, PLLC, Lockhart, Texas, performed an autopsy of the pilot. The autopsy report stated that the cause of death was "fresh water drowning." The FAA Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicological testing on the pilot. No carbon monoxide was detected in blood (femoral), cyanide testing was not performed, no ethanol was detected in vitreous, amlodipine was detected in liver and in blood (femoral). Amlodipine is a blood pressure control medication that is not generally considered impairing. Based upon the 1535 recorded weather, the density altitude was about 1,314 ft. According to the pilot's logbook, his last flight entry was a flight review in a Piper PA-28R-200 on December 21, 2016; the duration was 1.1 hours. The entry did not have a flight review endorsement by the flight instructor who provided the review. The Federal Aviation Administration (FAA) had no record of any previous accidents, incidents, or enforcement actions for the pilot. The pilot's brother-in-law stated that the pilot had previously landed at the airport "several times" because the airplane received 2 or 3 annual inspections at 30TX. The mechanic held an airframe and powerplant mechanic certificate with inspection authorization, which was renewed on March 17, 2017, by an FAA inspector from the San Antonio flight standards district office (SAT FSDO). The FAA had no record of any previous enforcement actions against the mechanic. The airplane was completely submerged and inverted in an 18- to 20-ft-deep pond that was about 80 to 100 ft from with the departure end of the runway 18. While inverted, the airplane nose was pointing toward the runway. The bottom of the fuselage had a longitudinal tear along its left side that extended from the firewall to the left wing trailing edge, consistent in width with a round barbed wire metal fence post that was between the runway and the pond and was bent over about 30° toward the pond. About the upper 8 inches of the post exhibited paint transfer from the airplane. The airplane cockpit/cabin door had been opened by a diver using the top and side latches. Postaccident examination of the door latches revealed that the door was able to be opened using the top and side latches. There was no binding of the door during its opening or closing. Ground scars consistent with skidding from the main landing gear wheels were present along the last 300 ft of runway 18. A ground scar was in front of the post, which was consistent with the airplane tailtie-down that was broken off the airplane. The barbed wire fence was not attached to the airplane nor was it wrapped around the propeller. The wing flaps were in the 40° extended position. One blade of the two-bladed metal propeller exhibited spanwise scratches that were angled about 20° to 45° relative to the blade chord, consistent with rotation. The second blade was straight. Neither blade exhibited S-shaped bending consistent with torque. Examination of the cockpit revealed that the magneto key switch was in the "both" position, the master switch was in the "on" position, the auxiliary fuel pump switch was in the "on" position, and the engine primer was in and locked. The cockpit throttle control was near the idle position, and the cockpit mixture control was about ¾ forward of the idle cut off position. The cockpit flap selector was in the 40° position. The shoulder harness for the left pilot seat was stowed to its ceiling retainer. Examination of the flight control system confirmed flight control continuity from all the control surfaces to left and right seat cockpit flight controls. The tailcone cover did not exhibit accident-related impact damage. All eight tailcone cover retaining screw holes along the longitudinal axis of the airplane had vertical cracks from the hole edges and through the cover. The four tailcone cover screws that were perpendicular to the longitudinal axis of the airplane were dark brown, consistent with long-term corrosion and non-recent removal. The screw heads were stripped. The tailcone was removed to expose the underlying flight control system components: the rudder cable ends, the stabilator trim screw, the stabilator screw/tab links, the stabilator hinge points, and the rudder trim assembly. These components exhibited a dry appearance, consistent with a lack of lubrication. According to the Piper Cherokee Service Manual, the components are to be lubricated every 100 hours with MIL-L-7870 and Aero Lubriplate lubricants. Examination of the electrically driven fuel pump revealed that it operated with no mechanical anomalies when tested on the airplane by the turning the airplane master switch and auxiliary fuel pump switch on and by removal and connection of the pump to an automotive battery. Testing of the pump before its removal from the airplane revealed that the cockpit fuel pressure gauge was inoperative. The three-position cockpit fuel selector control handle was positioned to the left fuel tank. The fuel selector handle did not turn freely using hand pressure through repetitive selections to the left fuel tank, right fuel tank, and off positions. The cockpit fuel selector had to be placed in a vice and a wrench used to remove the plastic fuel selector plug valve, with difficulty from the valve body. The valve stem exhibited a dull white colo,r consistent with oxidation. No obstruction to the attached ports for the fuel lines or when the valve was selected to all three positions was found. Examination ofthe engine revealed that the fuel and oil lines were intact. The engine sump contained liquid consistent in appearance with that of engine oil and water. The top and bottom plugs were removed, and the engine was rotated through when rotated by hand. During rotation, air was drawn into and expelled through the spark plug holes. Engine continuity to the accessory section, valve train, and drive train was confirmed. The spark plugs each had their electrodes intact and displayed features of normal operation as depicted in Champion Aerospace Aviation Service Manual V6-R, August 2014, Electrode Conditions. The engine-driven fuel pump was removed and actuated by hand pressure. It produced suction and expulsion of air through the pump inlet and outlet ports. Disassembly of the pump revealed that the pump diaphragm had no debris. The air inlet hose leading to the carburetor was SCAT hose (air duct hose commonly used for heating and cooling), which was the incorrect part for the application and installation. The hose did not exhibit impact damage and was collapsed. The right exhaust pipe bolt leading to the heat exchanger/muffler could not be unscrewed, and the pipe had to be cut for the heat exchanger to be examined. The heat exchanger housing had two repairs, one was a weld and the other was a riveted square metal patch. The heat exchanger exhaust was blocked about 50 percent with fractured internal heat exchanger pieces. The fracture surfaces of the blockage were brown in color, consistent with a long-term preexisting fracture. The Piper Cherokee Service Manual stated that the heat exchanger/muffler is to be replaced at or near 1,000 hours time-in-service. The engine timing was 27° top dead center (TDC); the engine data plate specified an engine timing of 25° TDC. The left magneto (Slick Magneto, model 4371, serial number 01120168) was manufactured in 2001, and the right magneto (Slick Magneto, model 4250, serial number 7090045) was manufactured in 1970. The left magneto did not spark, and the right engine magneto did not turn freely and exhibited corrosion of its bearing. The magnetos were examined at Navajo Accessories, Inc., San Antonio, Texas, under the supervision of the FAA inspector from the SAT FSDO. The left magneto exhibited corrosion on the impulse coupling, and the unit was nonfunctional. The rotor was worn and had flat spots. The points were seized and nonfunctional. The right magneto rotor and bearings exhibited corrosion, the capacitor wire was pinched and broken, the points were seized, and the coil was "obsolete." Both magnetos were issued red tags as not serviceable. The flexible fuel line leading to the carburetor was hardened and difficult to bend using hand pressure. The fire sleeve for the flexible fuel line was removed exposing its date code showing that it was manufactured in 1971. According to the airplane service manual, the flexible fuel lines are to be replaced or overhauled as required or at engine overhaul. The PiperCherokee Service Manual stated that flexible fuel lines are to be inspected at 100-hour intervals and replaced as necessary. Examination of the carburetor was performed at RLB Accessories, Addison, Illinois under the supervision of the National Transportation Safety Board investigator-in-charge. The examination revealed that the throttle arm shaft was loose due to wear. The fuel screens did not contained debris. The float was a metallic brass float that exhibited a float travel of about half of the required 7/32-inch travel. The RLB Accessories representative stated that the brass float should have been replaced in accordance with a service bulletin issued about 1990. The carburetor needle valve had the incorrect cotter pin installed. The gap distance between the throttle body valve and the carburetor throat body when in a closed position was 4/1000 inch but should have been about 20/1000 inch. The carburetor drain plug had safety wire in place. The RLB Accessories representative stated that the engine should have been washed as part of annual inspection but was not washed based on the external condition of carburetor. The representative stated the condition of the carburetor should have resulted in the engine operating with a rich fuel mixture. The airplane emergency locator transmitter (ELT) was not present in the airplane and ELT's retaining hardware was undamaged and in an open/unretained position. ## Aircraft - Registration: [N4329T](https://openairdocs.org/deregistered/N4329T-2020-05-29), registration cancelled 2020-05-29, S/N 28-7225146, built 1971 (OpenAirDocs) - Reported make and model: PIPER PA-28-140 - Registry model: [Piper PA-28-140](https://openairdocs.org/model/piper-pa-28-140) (registry code 7102802) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28-7225146 - Year built: 1971 - Airframe hours: 5063.72 - Engines: Lycoming O-320-E3D 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pilot (Co-owner) - Registered owner: Pilot (Co-owner) - Airworthiness certificate: Standard, Normal; Standard, Utility - Last inspection: Annual, March 25, 2017, 0 hours before - Departed: 30TX, Stonewall, TX - Destination: BAZ, New Braunfels, TX - Airport: 30TX, Burg Lake Aero Airport, runway 18, 2,200 × 160 ft, grass/turf ## Flight crew As NTSB recorded them.
