Thanks for posting that PyroTek -I too was wondering what the L a FMOST was...
In the scenario under discussion here, the FMOST check as indicated could have made the problem worse!!! The aircraft has/had turbocharged, injected engines, on which in some cases, it is necessary to lean the mixture from the cruise setting to achieve an engine-restart in flight, when fuel supply has (for whatever reason) been interrupted. I would expect that an appropriate in-flight restart procedure would have been discussed and demonstrated as a part of the endorsement training.
The FMOST check is quite probably very appropriate for a normally aspirated, carburetted engine. That does not mean it is necessarily appropriate for every reciprocating engine. A radial engine for example may well require yet another technique for an in-flight restart.
Worth keeping in mind.

Thanks Pyro.
Always amazes me why we have to have a mnemonic for every activity. Sometimes it is harder to remember the mnemonic than it is to remember the actions.
In that one (FMOST).
The first action is instinctive.
The second not necessarily a good idea.
The third is a normal instinctive scan (where else would you be looking as that thing on the wing is coughing and farting).
Which leaves you two actions for which you have this strange word association.
Intriguing.
For years we managed to get around without the benefit of the Jacobsen Flare and all manner of new fandangles. Good luck I guess, cos we were obviously ignorant.

I would have thought that most PA31/C310/C402 drivers, knowing that they need to use fuel from mains and auxs to complete the flight, would have instantly realised their **** up when the first engined surged and gone - change tanks, pumps on - and the problem would have been solved almost instantaneously!
I always staggered my tank changes on multi-tank aeroplanes like Aztecs, older Barons, PA31, C310/402 to avoid the likelihood of draining both sides dry at the same time.
Should almost be a **** up of a bigone era with most drivers now carrying portable GPS's that can be programmed to remind you to attend to fuel needs at set intervals.

Could even go 1 further than that. The most basic airmanship to begine with KEEP A FUEL LOG!. You know what is in their to start with, you know what your taxi and climb allowance is and in cruise with it all leaned out the FF gauge tells you what the motors are burning.
Only 3 things to keep a fire going which we all know, fuel air and spark take one away and it dont work no more! I was taught FMOST but really common sense should prevail. The motor has surged and stopped, now theres no oil all over the windscreen and no hole in the cowl where a piston has just shot through. So you would have to investigate the things that make the fire. Common sense?
