hull burnthrough and total loss of pressurization). Hull burnthrough has been present in all onboard oxygen fires except where bottles have exploded out through the hull (QANTAS 747-400 incident that diverted to Manila).

an unsafe condition for certain Airbus Model A319-115 and A319-133 airplanes. The MCAI states:
Following an ECAM [electronic centralized aircraft monitor] warning "CARGO SMOKE" during flight, the flight crew elected to divert and the aeroplane made an uneventful landing. The post-flight inspection evidenced a heavy fire in the vicinity of the Gaseous Oxygen System (GOS) for passengers, located close to the cargo area. The origin of the fire has not been clearly identified. After more investigation, Airbus determined that the current optional passenger GOS design, specific to A319 aeroplanes, is not robust enough to prevent further events of this kind.
This condition, if not detected and corrected, could lead to an uncontrolled fire, possibly resulting in loss of the aeroplane.
To address this potential unsafe condition, Airbus developed mod 153555 to improve the (optional) A319 GOS for passengers and published Service Bulletin (SB) A320-35-1062 to provide that modification for in-service application.
Consequently, EASA issued AD 2013-0153 to require modification of the passenger GOS installation.
