On August 29, 1982, a Grumman AA-1 (registration N5788L) operated by Sidney C. Irby was involved in an aviation accident near Pearland, TX. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot experienced engine roughness during a pre-takeoff run-up, which stopped after leaning, but inadequate thrust after liftoff led to a forced landing into a ditch and trees; the aircraft hit railroad tracks, shearing off the nose and left main gear.
Pilot Report
The pilot stated that during an engine run-up before takeoff, the engine ran rough on one magneto (which magneto was not specified). After the engine was leaned, the roughness ceased, and the pilot proceeded with takeoff. Following liftoff, thrust was insufficient to produce a climb. The pilot was able to clear a ditch and some small trees before being forced to land.
Accident Sequence
During the landing roll, the aircraft struck a railroad track, which sheared off the nose gear and the left main landing gear.
Witness Accounts
Ground witnesses reported that the engine was running rough throughout the taxi, run-up, and takeoff phases.
