## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE AIRCRAFT WAS BEING OPERATED BY A STUDENT PILOT AS AN INSTRUCTIONAL FLIGHT ON HIS SECOND SOLO. THIS WAS THE THIRD TAKEOFF OF THE SOLO EVENT. AT ABOUT 350 FEET AGL THE PILOT HEARD A LOUD POP. THE ENGINE BEGAN TO SHAKE VIOLENTLY, AND A LOSS OF POWER WAS NOTED. THIS CAUSED A FORCED LANDING IN A FIELD NEAR THE PRINCETON MUNICIPAL AIRPORT (PNM), PRINCETON, MINNESOTA. UPON INITIAL TOUCHDOWN THE AIRCRAFT FLIPPED OVER CAUSING SUBSTANTIAL DAMAGE. UPON RECOVERY OF THE AIRCRAFT IT WAS NOTED THAT THE #2 CYLINDER WAS MISSING THE LOWER SPARK PLUG AND HELICOIL.

## The NTSB's investigation of this event (1)

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 CEN12LA077](https://openairdocs.org/ntsb/CEN12LA077), Nov 22, 2011: Cessna 152 (N6436P), Princeton, MN, substantial damage. Probable cause: The inadequate installation of the threaded insert in the No. 2 cylinder spark plug hole by maintenance personnel, which resulted in a loss of engine power during initial climb.
