From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Aircraft departed Houma airport on a local training flight and flew to the nearby Houma-Terrebonne VOR to practice holding. Shortly thereafter, the crew noticed the oil temperature rising and the oil pressure falling on the right engine. The crew elected to shut down the right engine and return for landing. The pilot flying privacy data omitted instructed the non flying pilot privacy data omitted to delay extending the landing gear until on final approach for landing to avoid the possibility, as he explained, of having to do a single engine go around with the gear down. On final, the non flying pilot commenced landing gear extension but apparently mismanaged the actuating levers resulting in an "out of sequence" condition. The gear did not extend but failed to achieve a down and locked condition. Both crew stated they failed to get a green light in the cockpit indicating gear to be down and locked. Although the nonflying pilot advised he could not get the gear to lock, the flying pilot felt he was committed to landing and did so. On touchdown, the gear stayed down but on completion of the landing rollout, the pilot flying elected to turn off the runway at which point both main gear collapsed.

As the FAA filed it

(-23) AIRCRAFT DEPARTED HOUMA AIRPORT ON A LOCAL TRAINING FLIGHT AND FLEW TO THE NEARBY HOUMA-TERREBONNE VOR TO PRACTICE HOLDING. SHORTLY THEREAFTER, THE CREW NOTICED THE OIL TEMPERATURE RISING AND THE OIL PRESSURE FALLING ON THE RIGHT ENGINE. THE CREW ELECTED TO SHUT DOWN THE RIGHT ENGINE AND RETURN FOR LANDING. THE PILOT FLYING ^PRIVACY DATA^ INSTRUCTED THE NON FLYING PILOT ^PRIVACY DAT^ TO DELAY EXTENDING THE LANDING GEAR UNTIL ON FINAL APPROACH FOR LANDING TO AVOID THE POSSIBILITY, AS HE EXPLAINED, OF HAVING TO DO A SINGLE ENGINE GO AROUND WITH THE GEAR DOWN. ON FINAL, THE NON FLYING PILOT COMMENCED LANDING GEAR EXTENSION BUT APPARENTLY MISMANAGED THE ACTUATING LEVERS RESULTING IN AN "OUT OF SEQUENCE" CONDITION. THE GEAR DID NOT EXTEND BUT FAILED TO ACHIEVE A DOWN AND LOCKED CONDITION. BOTH CREW STATED THEY FAILED TO GET A GREEN LIGHT IN THE COCKPIT INDICATING GEAR TO BE DOWN AND LOCKED. ALTHOUGH THE NONFLYING PILOT ADVISED HE COULD NOT GET THE GEAR TO LOCK, THE FLYING PILOT FELT HE WAS COMMITTED TO LANDING AND DID SO. ON TOUCHDOWN, THE GEAR STAYED DOWN BUT ON COMPLETION OF THE LANDING ROLLOUT, THE PILOT FLYING ELECTED TO TURN OFF THE RUNWAY AT WHICH POINT BOTH MAIN GEAR COLLAPSED.
