## Other investigations on N38926 (5)

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.

- [NTSB SEA05LA138](https://openairdocs.org/ntsb/SEA05LA138), Jul 5, 2005: Bell 47G-2A (N38926), Oroville, WA, substantial damage. Probable cause: The failure of the throttle cable housing, which permitted the engine's RPM to decay to the idle position. Contributing factors were the trees and the lack of suitable terrain for a forced landing.
