# NTSB MIA99LA083: Beech A24R, N24624, Philadelphia, MS, February 13, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: February 13, 1999, 06:30 local (12:30 UTC) - Place: Philadelphia, MS - Coordinates: 32.770256, -89.100471 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.7703&lon=-89.1005&mi=10 - Phase of flight: [Taxi](https://openairdocs.org/ntsb-phases/250) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report April 20, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 45779 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA99LA083 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45779/pdf - Page: https://openairdocs.org/ntsb/MIA99LA083 ## Probable cause The failure of the pilot to ensure the aircraft tie down ropes were free from the aircraft prior to taxiing. This resulted in the aircraft turning uncontrolled when taxi was initiated due to a partially tied left wing, the pilot loosing control of the aircraft, and the aircraft colliding with a ditch and a tree. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, taxi - to takeoff - ground tie-down rope/strap - not removed, pilot in command (cause) - On ground/water encounter with terrain/water, taxi - terrain condition - ditch - On ground/water collision with object, taxi - object - tree(s) ## Analysis The pilot stated he had trouble getting the knotted tie down rope through the left wing tie down fitting when he parked the aircraft the night before the accident. On the morning of the accident he did not recall struggling to get the rope free from the fitting. As he started to taxi the aircraft jerked to the left and he inadvertently advanced the throttle. The aircraft ran into a ditch and then collided with a tree. ## Factual narrative On February 13, 1999, about 0630 central standard time, a Beech A24R, N24624, registered to an individual, collided with a ditch and a tree during taxi to takeoff at Philadelphia Airport, Philadelphia, Mississippi, while on a Title 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot received minor injuries. The flight was originating at the time of the accident. The pilot stated he had trouble getting the left wing tie down rope through the wing tie down fitting the night before the accident, due to a knot in the rope. As he added a quart of oil to the engine during the preflight inspection he remembers untying the tie down ropes. He does not remember struggling with the left tie down rope to get the knotted end back through the fitting. He completed the preflight inspection, got in and started the engine. As he applied engine power to begin taxiing, the aircraft jerked to the left and he was thrown toward the middle of the aircraft. He believes he pushed the engine throttle further forward as the aircraft jerked. The aircraft continued to move across the ground and he reduced the engine throttle to idle. He thought he had regained control of the aircraft and became distracted by the landing gear in transit light which had illuminated. The aircraft continued to move forward and went into a ditch and collided with a tree. ## Aircraft - Registration: [N24624](https://openairdocs.org/deregistered/N24624-2013-08-19), registration cancelled 2013-08-19, S/N MC-137, built 1972 (OpenAirDocs) - Reported make and model: Beech A24R - Registry model: [Beech A24R](https://openairdocs.org/model/beech-a24r) (registry code 1151252) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: MC-137 - Engines: Lycoming IO-360-A1B6 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Edmund A.

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.
