## NTSB investigations (73, newest 50)

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 CEN16CA383](https://openairdocs.org/ntsb/CEN16CA383), Sep 11, 2016: Mooney M20D (N6919U), Brodhead, WI, substantial damage. Probable cause: The pilot's loss of airplane control during initial climb due to an excessively nose-high attitude. Contributing to the accident was the pilot's failure to properly set the elevator trim before…
- [NTSB ERA09FA311](https://openairdocs.org/ntsb/ERA09FA311), May 29, 2009: Mooney M20D (N6628U), Clintwood, VA, substantial damage, 1 fatal. Probable cause: The pilot’s continued visual flight into instrument meteorological conditions, which resulted in controlled flight into terrain.
- [NTSB DFW08CA230](https://openairdocs.org/ntsb/DFW08CA230), Sep 12, 2008: Mooney M20D (N6646U), Grand Saline, TX, substantial damage. Probable cause: A loss of engine power for undetermined reasons. Contributing to the accident was the lack of suitable terrain for a forced landing.
- [NTSB SEA07CA268](https://openairdocs.org/ntsb/SEA07CA268), Sep 12, 2007: Mooney M20D (N1229X), Placerville, CA, substantial damage. Probable cause: The pilot's failure to extend the landing gear prior to landing. A contributing factor was the pilots impaired performance.
- [NTSB LAX07CA098](https://openairdocs.org/ntsb/LAX07CA098), Mar 3, 2007: Mooney M20D (N6628U), Visalia, CA, substantial damage. Probable cause: The pilot's inadequate in-flight fuel system management, which resulted in fuel starvation and a loss of engine power.
- [NTSB DEN04FA134](https://openairdocs.org/ntsb/DEN04FA134), Sep 6, 2004: Mooney M20D (N1907Y), Pagosa Springs, CO, destroyed, 1 fatal. Probable cause: the pilot's inadequate preflight planning and his failure to maintain directional control. Contributing factors were the pilot's failure to abort the takeoff, and the rough and uneven runway surface.
- [NTSB SEA03LA176](https://openairdocs.org/ntsb/SEA03LA176), Aug 24, 2003: Mooney M20D (N6619U), Hood River, OR, substantial damage. Probable cause: A power loss due to a mis-seated intake valve on the #1 cylinder resulting in leakage during the compression stroke and low compression. Contributing factors were the rising terrain and trees.
- [NTSB LAX03LA085](https://openairdocs.org/ntsb/LAX03LA085), Jan 24, 2003: Mooney M20D (N6639U), Casa Grande, AZ, substantial damage. Probable cause: Collapse of the landing gear during landing rollout, resulting from the pilot/mechanic's incorrect landing gear locking mechanism (linkage) adjustment.
- [NTSB IAD01LA033](https://openairdocs.org/ntsb/IAD01LA033), Feb 6, 2001: Mooney M20C (N1914Y), Peckville, PA, substantial damage. Probable cause: loss of engine power for undetermined reasons.
- [NTSB LAX00LA222](https://openairdocs.org/ntsb/LAX00LA222), Jun 8, 2000: Mooney M20D (N31M), Baker, CA, substantial damage. Probable cause: The fuel flow became restricted by remnants of fuel tank sealant that had accumulated in the fuel selector screen.
