You're barking up the wrong tree. The pilots didn't do the RFM mandatory after-start hydraulic checks ELEVEN TIMES in the previous 14 engine starts. Pilots who don't do the required flight critical checks, or who do them but don't understand what they are doing or why, are the naive ones. Not me. Whilst the stick jump check, even if done properly, might not have revealed the leaking hydraulic actuator immediately prior to the accident flight (because both sides of the faulty servo were leaking about equally), by not doing the check they certainly missed an opportunity to discover the problem. And through the history of that servo being installed on that aircraft, I find it impossible to believe that at some point in the past, as the servo condition deteriorated over time, that not a single after-start hydraulic check revealed any problem. That servo had been leaking for a long time, the hydraulic fluid had been contaminated for a long time, yet nobody knew. All because proper procedure hadn't been followed.
