# NTSB LAX94LA315: Piper PA-28R-201T, N9044A, Overgaard, AZ, August 11, 1994 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: August 11, 1994, 15:00 local (22:00 UTC) - Place: Overgaard, AZ - Coordinates: 34.369018, -110.479339 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.3690&lon=-110.4793&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report May 18, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 28823 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX94LA315 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/28823/pdf - Page: https://openairdocs.org/ntsb/LAX94LA315 ## Probable cause the pilot's failure to maintain an adequate airspeed margin, which resulted in an inadvertent stall. Factors in the accident were weather conditions, high density altitude, and shifting wind conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, approach - vfr pattern - final approach - weather condition - crosswind (contributing factor) - weather condition - gusts (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - airspeed - inadequate, pilot in command (cause) - stall - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis THE PILOT REPORTED DIVERTING AROUND RAIN SHOWERS ALONG THE ROUTE OF FLIGHT TO THE AIRPORT. ON FINAL APPROACH, ABOUT 10 FEET ABOVE THE GROUND, A GUST OF WIND BLEW THE AIRPLANE LEFT OF THE RUNWAY CENTERLINE. THE PILOT APPLIED FULL POWER IN ORDER TO GO-AROUND. THE AIRPLANE'S TURBOCHARGED ENGINE WAS IN THE PROCESS OF ACCELERATING AND DID NOT RESPOND IMMEDIATELY WITH FULL POWER, SO THE PILOT ENTERED A RIGHT TURN TO AVOID STRIKING AN OBSTRUCTION. THE AIRPLANE STALLED AND STRUCK THE GROUND ON THE RIGHT WING. THE ELEVATION OF THE AIRPORT IS 6,657 FEET ABOVE MEAN SEA LEVEL. THE CLOSEST OFFICIAL WEATHER OBSERVATION STATION, ABOUT 23 MILES AWAY, WAS ALSO REPORTING RAIN SHOWERS IN THE AREA. THE DENSITY ALTITUDE WAS CALCULATED AT 9,200 FEET. ## Factual narrative On August 11, 1994, at 1500 hours mountain standard time, a Piper PA-28R-201T, N9044A, collided with terrain after an in-flight loss of control on final approach to runway 20 at the Mogollon Airpark, Overgaard, Arizona. The airplane was being operated by Jandr Associates, Inc., Pahrump, Nevada, as a business flight under 14 CFR Part 91. The airplane sustained substantial damage. The certificated private pilot and passenger received minor injuries. The flight originated in Chino, California, at 1155 hours. Visual meteorological conditions prevailed at the time. The pilot diverted around rain showers along the route of flight from Chino to the Mogollon Airpark. After entering the Mogollon Airpark traffic pattern, the pilot observed the airport's windsock. According to the pilot, the windsock favored runway 20 with light winds. On final approach, about 10 feet above the ground, a gust of wind blew the airplane left of the runway centerline. The pilot applied full power in order to go-around. The airplane's powerplant did not respond immediately and the pilot entered a right turn to avoid striking an obstruction. The airplane stalled and struck the ground on the right wing. The elevation of the Mogollon Airpark is 6,657 feet above mean sea level (msl). The closest official weather observation station is the Show Low Airport, Show Low, Arizona, which is located about 23 nautical miles east of the accident site. The elevation of the weather observation station is 6,412 feet above msl. At 1442 hours, a record surface observation was reporting a temperature of 74 degrees Fahrenheit, with winds from 160 degrees at 10 knots. Remarks in the observation indicated thunderstorms to the southeast moving south with occasional light rain showers, and moderate rain showers observed in all quadrants. ## Aircraft - Registration: [N9044A](https://openairdocs.org/deregistered/N9044A-1994-10-03), registration cancelled 1994-10-03, S/N 28R7803253 (OpenAirDocs) - Reported make and model: PIPER PA-28R-201T (PA-28R-201) - Registry model: [Piper PA-28R-201T](https://openairdocs.org/model/piper-pa-28r-201t) (registry code 7102813) (OpenAirDocs) - Category: Airplane - Serial number: 28R-7803253 - Airframe hours: 1437 - Engines: CONTINENTAL TSIO-360F 200 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Registered owner: Jandr Associates, Inc. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 10, 1994, 31 hours before - Departed: CNO, CHINO, CA - Airport: AZ82, Mogollon Airpark, runway 20, 5,000 × 50 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
