Narrative:
Tunisair flight TU7045, a Boeing 737-6H3, diverted to Munich Airport, Germany after a loss of cabin pressure during the climb to cruise altitude. The aircraft had departed runway 24 of Prague Airport at 09:25 UTC
The aircraft was climbing through FL320 as it entered German airspace at 09:39 UTC. At that time cabin pressure dropped and the oxygen masks released in the passenger cabin.
The flight crew initiated an emergency descent to FL100, which was approved by the Munich Radar controller. A decision was made to divert to Munich, where a safe landing was made on runway 26L at 10:05 UTC.
The reason for the pressure loss was a leaky valve in the transition area from the APU to the cabin (Bulk Seal on the Keel Beam of the APU Bleed Duct). Another leakage was found in the area of the L/H pack.
