No, it's not. I have had a number of SAFA inspections, and they were nothing like this.
It is also unacceptable for the inspectors to delay a flight unless they find a major problem.
I agree however my most 'thorough' ramp check took place in JFK where apart from the normal checks and procedures we were asked to derive a ZFW from the load and balance manual, demonstrate a BITE test of the EGPWS system (??? never done that before!) and explain our understanding of the TCAS system. All a bit odd.
Then the inspectors declared that they had found one of the PCA access panel quick release fasteners open and wanted the complete PCA ramp history of the aircraft to find who left it open and demanded to know why it hadn't been seen on the walk around.
It took 30 minutes of demonstrating that the latch can 'look' closed but not be fully seated before the inspector grudgingly acceded that no misdemeanor had occurred on the walk around!
It often depends upon how difficult a day the inspectors have had as, with the best will in the world, they are the last people you want to see on the gate when you put the park brake on!!!
