Upon reading the report of the events leading up to the accident it is very clear that standards have slipped at the Red Arrows and that things were rushed and over looked.
The pilot had taken over the counter medication, he was not current in two areas of training, he couldn't find his flying jacket so did without it, he took a call on his mobile when walking out to the aircraft, the RA allowed 3 mins to complete checks when other forces allow 5, he failed to remove two safety items until reminded to do so by his ground crew. RT procedures were not followed. IMHO it appears that standards have slipped at the unit and could have been a contributing factor.
The close tolerance with the shackle was a well known manufacturing/service problem known to many operators who use the same seat and though recommendations were made there was no real RED FLAG alert in place.
It is easy to become complacent when you are 'The best of the best' but the whole team
need to reassess their standards and strive to achieve a higher standard.
