# NTSB IAD97LA031: Mooney M20F, N3424N, Wellsville, NY, December 11, 1996 - Type: NTSB accident investigation - Classification: Accident · Fatal · Limited investigation · Final report - Date: December 11, 1996, 16:20 local (21:20 UTC) - Place: Wellsville, NY - Coordinates: 42.119102, -77.939674 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=42.1191&lon=-77.9397&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Fatal - Injuries: 2 fatal, 1 serious - Status: Completed, report November 6, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 28166 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=IAD97LA031 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/28166/pdf - Page: https://openairdocs.org/ntsb/IAD97LA031 ## Probable cause Descent below the published minimum descent altitude followed by collision with the surrounding terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, approach - faf/outer marker to threshold (ifr) - weather condition - below approach/landing minimums (contributing factor) - minimum descent altitude - not maintained, pilot in command (cause) ## Analysis Instrument meteorological conditions prevailed at the destination. After picking up another passenger and refueling, the pilot departed for their destination. The surviving passenger stated that the pilot was utilizing his Global Positioning System (GPS) en route to help track their route to their destination. The destination airport was equipped with a Localizer approach to the runway. The passenger reported that there was no indication from the pilot that anything was wrong with the airplane, the engine sounded good and there was no ice on the airplane. As they approached the airport, the surviving passenger heard the pilot state, 'I can see the ground' and the pilot gave the thumbs up signal. This statement was followed by the front right seat passenger exclaiming, 'Look out for the trees, pull up, pull up!' There was no power application and shortly afterwards the airplane collided with the trees. ## Factual narrative On December 11, 1996, approximately 1620 eastern standard time, a Mooney, M20F, N3424N, was destroyed when it collided with the terrain during an approach to the Wellsville Municipal, Tarantine Field, Wellsville, New York. The certificated private pilot/owner and the passenger in the front seat received fatal injuries, the passenger in the back seat was seriously injured. Instrument meteorological conditions existed and a instrument flight rules flight plan was filed for the personal flight conducted under 14 CFR Part 91, which originated from Erie International Airport, Erie, Pennsylvania, at 1530. The surviving passenger reported that he occupied the front right seat when he flew with the pilot from Pottstown, Pennsylvania, to Erie, Pennsylvania, to pickup another passenger. The surviving passenger stated that he was seated in the back for the flight from Erie to Wellsville, New York. He stated that there was no indication from the pilot that anything was wrong, the engine sounded good, and there was no ice on the airplane. He remembered the pilot utilizing his Global Positioning System (GPS) during the flight. During the approach into the Wellsville Airport, the surviving passenger reported that he heard the pilot state, "I can see the ground" and gave the thumbs up signal. This statement was followed by the front right seat passenger exclaiming, "Look out for the trees, pull up, pull up!" The surviving passenger reported that there was no power application and they crashed shortly afterwards. The weather recorded by the Wellsville Municipal Automated Surface Observation System was: 1/4 mile visibility with light fog; Temperature: 35 degrees Fahrenheit, Dewpoint: 35 degrees Fahrenheit. A Federal Aviation Administration Inspector examined the wreckage. The examination revealed that the wreckage was approximately 400 feet south and 300 feet west of the departure end of runway 28. All pieces of the wreckage were in close vicinity and the path through the trees descending to the wreckage was parallel to the runway orientation. The Inspector confirmed flight control continuity and reported finding a yoke mounted GPS attached to the pilot's control column. The Wellsville Municipal, Tarantine Field had a Localizer Approach for runway 28. The Minimum Descent Altitude for this non precision approach with the local altimeter setting was 2,520 feet mean sea level, with the airport elevation at 2123 feet. The FAA conducted a flight check of the Localizer following the accident and found it to be operational. The toxicological testing report from the FAA Toxicology Accident Research Laboratory, Oklahoma City, Oklahoma, revealed negative for drugs and alcohol for the pilot. ## Aircraft - Registration: [N3424N](https://openairdocs.org/deregistered/N3424N-1998-06-10), registration cancelled 1998-06-10, S/N 680048 (OpenAirDocs) - Reported make and model: Mooney M20F - Registry model: [Mooney M20F](https://openairdocs.org/model/mooney-m20f) (registry code 5870214) (OpenAirDocs) - Category: Airplane - Serial number: 680048 - Engines: Lycoming IO-360 180 horsepower reciprocating - Damage: Destroyed - Flight: Personal, Part 91 - Registered owner: Peter J.

Crashed in a wooded area short of runway. From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
