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.

The pilot in command was flying from klew to kcrg at FL165, weather

Conditions were VMC. Cabin pressure differential was 4.9 PSI with a limit

Of 5.1 PSI. In the vicinity of kbed, there was a loud pop, followed by

Loud, cold wind. The PIC observed that the right/copilot window had

Departed the aircraft. At that time, he declared an emergency and

Descended to 3000 feet. The PIC observed normal control responses, and

That the instruments and avionics were functioning normally. He

Informed ATC that he would return to klew. He returned to klew and

Landed without incident.

The PIC is privacy data omitted. He stated that he had ordered

Replacement windows for his airplane after reading a report of an

Explosive decompression in a different airplane of the same model, as the

Accident airplane. The pilot, in the previous accident, flew the airplane

Back to home base safely. Following the decompression and departure of

The window from the airplane, the PIC descended to a safe altitude,

Conducted flight control, instrument and avionics checks prior to

Deciding to return to his home base, in lieu of landing at the nearest

Airport. An additional safety control measure that he had available was

An aircraft parachute, that could be used in the case that the airplane

Was no longer airworthy or controllable. The pic's judgement and actions

Were appropriate and safe. I recommend no action.

As the FAA filed it

THE PILOT IN COMMAND WAS FLYING FROM KLEW TO KCRG AT FL165, WEATHER

CONDITIONS WERE VMC. CABIN PRESSURE DIFFERENTIAL WAS 4.9 PSI WITH A LIMIT

OF 5.1 PSI. IN THE VICINITY OF KBED, THERE WAS A LOUD POP, FOLLOWED BY

LOUD, COLD WIND. THE PIC OBSERVED THAT THE RIGHT/COPILOT WINDOW HAD

DEPARTED THE AIRCRAFT. AT THAT TIME, HE DECLARED AN EMERGENCY AND

DESCENDED TO 3000 FEET. THE PIC OBSERVED NORMAL CONTROL RESPONSES, AND

THAT THE INSTRUMENTS AND AVIONICS WERE FUNCTIONING NORMALLY. HE

INFORMED ATC THAT HE WOULD RETURN TO KLEW. HE RETURNED TO KLEW AND

LANDED WITHOUT INCIDENT.

THE PIC IS ^PRIVACY DATA OMITTED^. HE STATED THAT HE HAD ORDERED

REPLACEMENT WINDOWS FOR HIS AIRPLANE AFTER READING A REPORT OF AN

EXPLOSIVE DECOMPRESSION IN A DIFFERENT AIRPLANE OF THE SAME MODEL, AS THE

ACCIDENT AIRPLANE. THE PILOT, IN THE PREVIOUS ACCIDENT, FLEW THE AIRPLANE

BACK TO HOME BASE SAFELY. FOLLOWING THE DECOMPRESSION AND DEPARTURE OF

THE WINDOW FROM THE AIRPLANE, THE PIC DESCENDED TO A SAFE ALTITUDE,

CONDUCTED FLIGHT CONTROL, INSTRUMENT AND AVIONICS CHECKS PRIOR TO

DECIDING TO RETURN TO HIS HOME BASE, IN LIEU OF LANDING AT THE NEAREST

AIRPORT. AN ADDITIONAL SAFETY CONTROL MEASURE THAT HE HAD AVAILABLE WAS

AN AIRCRAFT PARACHUTE, THAT COULD BE USED IN THE CASE THAT THE AIRPLANE

WAS NO LONGER AIRWORTHY OR CONTROLLABLE. THE PIC'S JUDGEMENT AND ACTIONS

WERE APPROPRIATE AND SAFE. I RECOMMEND NO ACTION.
