NTSB narrative

The airplane sustained substantial damage on impact with trees and terrain during a forced landing to a field following an in-flight loss of engine power. Skydivers had been dropped prior to the loss of engine power and the pilot reported no injuries. The pilot stated, "I climbed to 11000 [feet.] Was not getting usual climb rate[.] Before decent found I could not close cowl flaps. Decended to 6000 [feet.] Noticed eratic raise on manifold gage[.] Decided to shut down engine to stop further any possible damage. Flew down to pattern altitude where a plane flew in front of me and carried on across airport. I then carried on my landing, was about to turn base when I noticed the plane had turned 120 [degrees] and was flying toward me[.] I finally got hold of him on the radio and told him I had an engine out. He acknolaged and headed north out of the area. I then realized I was not able to get to runway because of high trees[.] Decided to turn into cleared area but hit tree with right wing[.]" Under mechanical malfunction failure, the pilot stated, "Air intake hose blown off after backfire[.]"

Probable cause

The misjudged in-flight planning the pilot had for the forced landing. Factors were the induction air ducting separation, the pilot not coordinating his emergency procedure with airfield traffic, and the trees.

  • 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2001-03-10.
