Safety issue
The current US Federal Aviation Administration approved
Supplemental Type Certificate SA2123NM supplemental operational
documentation relating to usage of the auxiliary fuel pump in the
Cessna U206 is ambiguous regarding the operation of the pump for
takeoff. That ambiguity could result in the inappropriate use of
the pump and subsequent engine operational issues.
ATSB comment
As at 24 November 2008, no further advice had been received from
the US Federal Aviation Administration on their consideration of
the recommendation and the ATSB reclassifies it as Closed - Not
Accepted.
Safety Recommendation
The Australian Transport Safety Bureau recommends that the US
Federal Aviation Administration require Aeromods Incorporated to
amend the aircraft operational documentation supplement for the
Cessna U206 aircraft relating to Supplemental Type Certificate
SA2123NM, to include information on the recommended use of the
auxiliary fuel pump for takeoff.
