NTSB narrative

The pilot had just purchased the airplane (2 hours flight experience in make and model; total flight time 118 hours) and was departing Alamogordo (elevation 4,197 feet; density altitude 6,741) for the cross-country trip home to California. The pilot reported that he performed a 'long engine run-up' and that the airplane 'lost power right after takeoff.' The airplane came to rest approximately 480 feet from the runway in rough, high vegetated terrain. The takeoff had been attempted at a weight of 1,431 pounds, and the designer recommended a maximum takeoff weight of 1,325 pounds. The engine was 29 years old with numerous time periods of storage with no documentation of preservation or overhaul according to manufacturer's recommendations. The engine was examined at the factory and the pistons revealed worn rings, heavy blow-by signatures, and scuffing on the piston skirts. The #3 piston had a record of low compression and exhibited black carbon deposits on top.

Probable cause

The improper maintenance procedures (failure to preserve the engine during numerous storage periods over 30 days) and the lack of suitable terrain for a forced landing. Factors were the pilot's lack of experience in type of aircraft and the high density altitude weather conditions.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
