Classic North American Aircraft Now Has A PMA Valve
Solution
Sierra Hotel Aero, Inc (SHA) owner of the Navion Type
certificate, announced last week it has received a supply of new
OEM approved fuel valves for immediate shipment to current Navion
operators. These valves support mechanics and owners in their
compliance with AD 2008-05-14. This fuel valve allows a simple log
book entry instead of requiring an FAA approval for each field
installation using non PMA approved valves.
Recently, the FAA adopted a new airworthiness directive (AD) for
all Sierra Hotel Aero, Inc. (formerly Navion Aircraft LLC) Models
Navion (L-17A), Navion A (L-17B), (L-17C), Navion B, Navion D,
Navion E, Navion F, Navion G, and Navion H airplanes. This AD
requires owners to conduct a one-time inspection of the entire fuel
system and repetitive functional tests of certain fuel selector
valves. This AD was a result of reports of airplane accidents
associated with leaking or improperly operating fuel selector
valves. The FAA issued this AD to detect and correct fuel system
leaks or improperly operating fuel selector valves, which could
result in the disruption of fuel flow to the engine and could lead
to engine power loss.
"This PMA valve makes it easier to document and install this
critical component as a new unit. We have seen old field repaired
valves fail. Now by using this valve, which is similar to that used
in new production Cirrus and Maule Aircraft, owners have the safety
of newer technology in a classic factory supported airframe." said
Chris Gardner, SHA owner.
Sierra Hotel Aero, based in South Saint Paul, MN, and has
responsibility and ownership of the North American Navion type
Certificate and services it and most other general aviation
aircraft with modifications and most types of field repairs.
