Narrative:
AAIB investigation to Beech 200 Super King Air, G-KVIP 26 July 2017: The aircraft cabin depressurised, en-route Exeter to Faro, Portugal, 26 July 2017. The exact location of the incident does not seem to have been noted; however, as the aircraft returned to Exeter, it can be presumed that the incident occurred over the western part of the English Channel, south of the coast of Devon. The incident was the subject of an AAIB Investigation, and the following is the summary from the AAIB Report:

"The aircraft was being flown from Exeter to Faro in Portugal and whilst passing FL275, cleared to FL280, the ALT warning illuminated on the flight deck. The passenger oxygen masks dropped down and the passengers successfully put them on. The pilot had difficulty donning his mask, which had become entangled on items behind the pilot’s seat. He informed ATC of the situation and carried out an emergency descent to FL100 and diverted back to Exeter, which was also the operator’s maintenance base. The return to Exeter was uneventful and a normal approach and landing was made on Runway 26. On shutting down the aircraft, the pilot felt unwell but he thought this may have been a result of the incident.

The maintenance organisation identified two sources of cabin pressurisation loss; the outflow valve and a landing gear seal. Both were replaced and an air test confirmed the problem was rectified. The operator issued a notice to aircrew reminding them to ensure the oxygen mask was unobstructed before flight, and a new mask holder was installed in the flight deck roof to ensure its unimpeded use".
