They also said that the propeller was rotating either slowly or had stopped, and they then observed the airplane enter a steep turn, followed by an abrupt and uncontrolled nose-low descent and subsequent impact with the ground. The airplane came to rest in a nose-low, near vertical position, suspended at its tail section by a fence and some trees along the eastern perimeter of the airport. It had incurred substantial damage and the pilot and two passengers who were onboard the airplane were fatally injured. Postaccident examination of the airframe, flight controls and the engine did not reveal any mechanical failure or malfunction. The flaps were found to have been set to 10 degrees, and the propeller showed little or no evidence of rotation at impact. The FAA Toxicology Laboratory, Oklahoma City, Oklahoma, performed toxicological studies on specimens obtained from the pilot and the results showed that diphenhydramine was found to be present in urine, and 0.139 (ug/ml, ug/g) diphenhydramine was detected in blood. Diphenhydramine, commonly known by the trade name Benadryl, is an over-the-counter antihistamine with sedative side effects, and is commonly used to treat allergy symptoms. Published research (Weiler et. al. Effects of Fexofenadine, Diphenhydramine, and Alcohol on Driving Performance. Annals of Internal Medicine 2000; 132:354-363), has noted the effect of a maximal over the counter dose of diphenhydramine to be worse than the effect of a 0.10% blood alcohol level on certain measures of simulated driving performance. The level of diphenydramine in the blood of the pilot was consistent with recent use of more than a typical maximum single over-the-counter dose of the medication. ## Factual narrative HISTORY OF FLIGHT On June 19, 2002, about 0958 eastern daylight time, a Piper PA-46-310P, N9127L, registered to and operated by a private individual, as a Title 14 CFR Part 91 personal flight, crashed shortly after takeoff from Naples Municipal Airport, Naples, Florida. Visual meteorological conditions prevailed, and no flight plan was filed. The private-rated pilot and two passengers received fatal injuries, and the airplane was destroyed. The flight was originating at the time of the accident. The mechanic who performed the annual inspection stated that after he completed the inspection, he tested the airplane by performing low and high power static tests for about 30 minutes. He further stated that all tests were normal, and he then endorsed the logbooks, and returned the airplane to service. While the annual was being conducted, the mechanic said that the pilot arrived with two passengers, and was anxious to proceed on his planned flight to St. Petersburg, Florida. After the airplane was returned to the pilot, the mechanic said he saw the pilot perform a short preflight, and then he and his passengers embarked the airplane, and taxied from the maintenance facility. Information obtained from the FAA Air Traffic Control Tower showed that from the time the pilot requested a clearance to taxi, to the time the clearance was issued for takeoff on the active runway, was about 5 minutes. The airplane was departing from runway 05, at Naples Municipal Airport, and according to witnesses, it was at a low altitude in the vicinity of the departure end of the runway, when all of a sudden it entered into a steep bank, followed by a nose-down pitch attitude, and subsequently it impacted the ground. One of the witnesses stated that when he saw the airplane he did not hear the engine operating, and it appeared as if the propeller was moving slowly. Another witness stated that when the noise of the airplane's engine ceased, it drew his attention to the airplane, and he then turned to see what was happening. He said he saw the airplane enter a steep bank to the right, and descend. The FAA Air Traffic Control Tower controller on duty at the airport stated that he had watched the accident airplane as it was cleared onto the active runway. He said he then saw it proceed down the runway and climb to an altitude of about 50-to 75 feet above the runway, but at that time his attention was diverted to inbound traffic. He said that there had been no further radio communications transmissions with the pilot of the accident airplane after the takeoff clearance had been issued. PERSONNEL INFORMATION The pilot/owner of N9127L held a FAA private pilot certificate, with airplane single and multiengine land and instrument ratings, last issued on October 25, 1993, when the multiengine rating was added. He also held an FAA third class medical certificate, issued on March 5, 2002. The pilot's medical certificate did not show any limitations. The NTSB did not obtain access to the pilot's flight logbook, but according to information obtained from his last FAA medical examination, the pilot stated that he had accumulated a total of 3,000 hours of flight experience at the time of his application for the medical certificate. AIRCRAFT INFORMATION N9127L, is a 1987 Piper Malibu, model number PA-46-310P, serial number 46-08102. The airplane was equipped with a Teledyne Continental Motors, TSIO-520-BE2G, 310 horsepower engine. It is also equipped with a Hartzell two-bladed constant speed propeller, model number CHC-2YF-1BF. At the time of the accident, records showed that the airplane had accumulated about 4,643.3 flight hours on the airframe, and about 898 hours on the factory rebuilt/zero timed engine. The airplane had last received an annual inspection on June 19, 2002, and this was the first flight since that inspection. METEOROLOGICAL INFORMATION Visual meteorological conditions prevailed at the time of the accident. The Naples Municipal Airport 0953, surface weather observation was, winds from 110 degrees at 4 knots, visibility 10 statute miles, few clouds at 2,000 feet, temperature 84 degrees Fahrenheit, dew point temperature 75 degrees Fahrenheit, altimeter setting 30.11 inHg. WRECKAGE AND IMPACT INFORMATION The airplane impacted the ground on airport property behind the Humane Society building, located at 160 Aviation Drive, Naples, Florida. The airplane came to rest in a nose-low, near vertical attitude, suspended at its tail section by a fence and some sparse trees along the eastern perimeter of the airport. The geographic position of the accident site was 26 degrees, 09.398 minutes north latitude, 081 degrees, 46.112 minutes west longitude, and the position is about 100 feet beyond the end, and about 400 feet to the right of the departure runway's centerline. All components of the airplane necessary to sustain flight, were located in the immediate vicinity of the main wreckage. The airplane had incurred impact damage to its nose areas, to include the propeller, spinner, cowling and engine. Compression wrinkles were evident, and the nose section had been pushed up, and to the rear. The aft fuselage/empennage, was been bent about 30 degrees from the vertical, but it otherwise had minimal damage. There were no indications of a fire and/or explosion having occurred at the scene. No evidence of any preaccident mechanical failure or malfunction to the airframe was found, and flight control continuity was established for roll and yaw. The elevator cable had parted, consistent with overload, and flight control continuity for pitch was confirmed from the elevator forward to the broken cable, and from the control yoke aft. The elevator trim tab actuator displayed seven threads, which equated to about a neutral setting. There was no damage to the tail cone, vertical fin/rudder, but the left horizontal stabilizer had been bent upward at the leading edge about 3 feet from the root. The left elevator was attached to the spar and the skin was wrinkled. The elevator "up-stop" had incurred impact damage, and the right stabilizer had incurred wrinkling about 4 feet outboard of the root. In the cockpit, the panel had been pushed up and aft into the cabin. The throttle control was found to be in the full forward position, and it was bent to the right. The mixture control was also bent slightly to the right, and was about a half inch from its forward stop. The propeller control was about half an inch from its aft stop and was also bent to the right about 90 degrees. The fuel selector lever was positioned to select the left tank, and the selector valve corresponded to the left tank as well. When tested, the fuel selector valve operated in the left, right, and off positions. The electric boost pump switch had incurred impact damage, and its position could not be determined. The main and nose landing gear were in the retracted position. The right rear of the fuselage, aft of the upper rear window frame had 12 rivets missing with 12 corresponding holes remaining in the fuselage. The right rear shoulder harness bracket that had been affixed to the fuselage in that position, and had separated from the fuselage. In addition, the corresponding right rear seatbelt webbing stitch which secured the webbing to the female end of the buckle had separated at the stitches. All seats exhibited signs consistent with impact damage. The left wing had remained attached to the fuselage, and its leading edge was twisted and had been pushed upward and aft. The outboard section of the leading edge exhibited accordion crushing. Portions of the upper skin had separated from the main spar rivet line, exposing the fuel tank. The upper aft inboard section of the wing was also wrinkled from the wing root, outboard. The aileron was still attached to the wing, but its edge was bent upward. The aileron connecting rod had separated also from the aileron. The flap remained at ## Aircraft - Registration: [N9127L](https://openairdocs.org/deregistered/N9127L-2003-06-04), registration cancelled 2003-06-04, S/N 4608102, built 1987 (OpenAirDocs) - Reported make and model: Piper PA-46-310P - Registry model: [Piper PA-46-310P](https://openairdocs.org/model/piper-pa-46-310p) (registry code 7104605) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 4608102 - Airframe hours: 4643.3 - Engines: Teledyne Continental TSIO-520-BE2G 310 horsepower reciprocating - Damage: Destroyed - Flight: Personal, Part 91 - Registered owner: Cavin Robert Councilor - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 19, 2002, 0 hours before - Departed: APF, Naples, FL - Destination: PIE, St. Petersberg, FL - Airport: APF, Naples Municipal Airport, runway 5, 5,000 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
