Great job by the crew
The report mentions the crew engaged the autopilot about three minutes after lift off. Nothing was said in the report about the wisdom or otherwise of engaging the autopilot even though it was obvious such a significant amount of rudder trim (eight degrees?) and aileron control was already needed. Tellingly, the captain had already stated the amount rudder trim needed was more than that normally used for engine failure.

Nowadays, opinions on crew airmanship rarely appears in official reports. Perhaps that is because of risks of litigation. That is a real pity since it is left to readers to make up their own mind on how they would have handled the situation, rather than read expert opinion from the investigation team who may have access to more information than currently appears in official reports.

In this incident there was a haste to engage the autopilot after take off despite every indication of a serious flight control problem? Another example of automation dependency, maybe? Or perhaps a company SOP mandating autopilot engagement as soon as practical after take off.

Similarly, while the skill of the first officer to undertake the subsequent landing was judged by the captain to be unquestionable, others may feel it would have been prudent for the captain to have taken over control early in the event and assumed command responsibility; particularly since an unknown defect was causing such significant control difficulties soon after lift off. While CRM is undoubtedly a laudable concept, captains should avoid the reputation of being perceived as "the good,ole boy" simply because it is the first officer's "leg". As it turned out, the incident was clearly a serious flight control anomaly especially as neither pilot knew at that stage the true cause of the defect.

This is not to decry the captain's assumed capability of the first officer to handle an emergency on "his leg" but rather to open up a discussion in these Pprune pages of the wisdom or otherwise of some command decisions within a multi-crew operation. The flight had a happy ending and presumably the crew were given a pat on the back. While the result perhaps justifies the captains decisions to give his first officer complete handling of the situation, some may have a different point of view? Hence this post.
