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.
