## Analysis

THE ACFT NOSED OVER AFTER CONTACTING AN UTILITY POLE DURING AN OVERRUN LANDING. THE ACFT TOUCHED DOWN APRX 1/2 WAY DOWN THE RWY AND THE PLT APPLIED BRAKES, HOWEVER, BRAKING ACTION WAS POOR BECAUSE OF THE WET GRASS RWY. THE ACFT SKIDDED OFF THE END OF THE RWY WHERE IT CONTACTED THE UTILITY POLE AND NOSED OVER.

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19850322010819A](https://openairdocs.org/incident/19850322010819A), Mar 22, 1985: Boeing 75, Marston Mills, MA, Substantial damage. Landed long on a wet grass runway. Had no braking traction. Slid off the runway end, hit a pole and nosed over.

## Other investigations on N3993P (2)

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 ERA12CA434](https://openairdocs.org/ntsb/ERA12CA434), Jul 7, 2012: Jones Peter M Boeing/Jones 75 (N3993P), Bayport, NY, substantial damage. Probable cause: The airplane’s encounter with a wind shift to a tailwind during takeoff, which resulted in the pilot’s decision to abort the takeoff and the airplane’s subsequent runway overrun.
