## Analysis

AS PART OF A GROUP OF A CONFEDERATE AIR FORCE ACFT THE FLIGHT CONDUCTED PUBLIC RELATIONS FLYOVERS AT SEVERAL AREA ARPTS. DUE TO A LOW LDG GEAR STRUT N63697 DID NOT LAND WITH THE OTHER ACFT AFTER THE FLYOVERS. THE PLT PLANNED TO HAVE THE STRUT REPAIRED UPON ARRIVAL AT HOBBS, NM. WHILE CIRCLING OVHD 2 INTERMEDIATE ARPTS, ENGINE OIL TEMP EXCEEDED THE RED LINE. THE PLT ATTRIBUTED THE RISE TO HIGH OAT AND SLOW SPEED. AFTER REFUELING THE ACFT DEPARTED ON THE LAST LEG TO HOBBS. ABOUT 15 MIN LATER HEAVY VIBRATIONS DEVELOPED IN THE ENGINE. POWER WAS REDUCED AND A FORCED LDG IN AN OIL FIELD ACCOMPLISHED. DURING THE LDG ROLL BOTH MAIN GEAR COLLAPSED.

## FAA reports on this event (1)

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

- [Accident 19840728035859A](https://openairdocs.org/incident/19840728035859A), Jul 28, 1984: Cvac BT13B, Hobbs, NM, Substantial damage. Crash occurred during emergency landing after engine failure. Origin of failure was in one of cylinders.

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.
