Biscuit,
Right after this tragedy occurred I asked the question why the Transfer Pumps were switched on and off at various stages of flight in the 135.
I have flown the 105 and 117 and once we turned the Transfer Pumps ON....they stayed ON until the Shutdown Procedure after landing.
Are there any real reason that could not be the policy for the 135?
I accept there might be additional wear on the Pumps over time but as they do have OverTemp protection....is there any absolute need to shut them off?
Had those Pumps been turned on at Engine Start and left on until the After Landing/Shut Down procedure....would that have had any effect upon the outcome of this accident?
