What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot detected a loss of pressurization while cruising at FL220. He made an emergency decento to 12,000 feet MSL. Ground inspection revealed that a steel clamp holding a 4 inch diameter flexible connection fitting had come loose and allowed the flexible hose to be blown off the pressurized delivery ducts. The flexible connecting hose may not have been overlapped enough or clamped tightly onto the metal duct, allowing it to blow off inflight. The hose and clamp were reattached. ZFWARTCC020 was the ATC incident control number on the FAA form 8020-11.
