The report found that there was a flaw with the fuel transmission to this right-hand side engine which could have been giving more power than the left-hand side engine. This means there was a potential for the plane to be unbalanced as it landed.
“The aircraft may well not have ended up inverted on its back had both engines been delivering equal and balanced power,” Healy-Pratt, from specialist aviation lawyers Stewarts Law LLP, said.
“Indeed the power imbalance probably resulted in one wing dropping and hitting the ground first, resulting in the aircraft rolling over.
The rigging is hardly Honeywells fault. Neither is the old engine new engines differences in power spool up.
Honeywell have actually quite a good pilot education program and also engineering thats quite reasonably priced.
It doesn't matter what limits the OEM put in the manuals if the operator doesn't spend the money on the maint your not going to have a pair of well rigged engines.
Rigging the engines takes a day for two engineers and also a test flight. Its normally done as required after some major maint with the control runs or after a heavy check.
