But can be interpreted many ways.
The aircraft is struck by lightning, and the ensuing inspection delays the flight. Technical? Not in my airline, it was DF
damaged in Flight.
The tyre is damaged driving over FOD on the taxy in. The wheel replacement delays the flight. Tech? No its DG
, damage on the ground.
The loaders drive into the engine nosecowl and the flight is Cancelled awaiting a spare. Tech? No its DG
and the loaders get the blame.
The aircraft has the APU inop. The doors are closed on time, but using an airstart to start the engines delays the departure. Technical? YES. We code these delays as TD
-Apu. The reason was to get maintenance to fix APUs to lose the delays. About 30pc of Tech delays are now APU caused!
The pilots call for maintenance, He arrives at the aircraft and finds no fault and the aircraft is delayed. Tech? No its FR
, flight crew.
But we do count delays from the first minute.
