3000 light a/c grounded in Oz, issues with gaskets
http://www.abc.net.au/news/stories/2...13/2188944.htm
The Civil Aviation Safety Authority has grounded up to 3,000 small planes until they are inspected for the risk of engine failure.
The authority says it is responding to an urgent directive put out in the United States last night to ground and inspect a range of piston-engine planes because of safety concerns.
A spokesman says up to 3,000 small planes with between four and 10 seats will be grounded around Australia tonight and will not be able to be flown until they have been inspected.
He says the problem is a faulty gasket which could lead to engine failure.
"The advice we got from the United States was that this is a very serious problem," he said.
"Aircraft should not be allowed to fly until they've been inspected and that's what we've mandated.
"The risk is an engine failure in flight and that's obviously too big a risk to take."
He says 18 incidents of engine failure have been reported in the United States.
The spokesman says a small number of the planes are used by charter passenger services and regional airlines.
He says no large commercial arlines have been affected.

Could be this FAA Emergency AD
"This emergency airworthiness directive (AD) 2008-06-51 is sent to all owners and operators of Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series reciprocating engines, Teledyne Continental Motors (TCM) TSIO-360-RB reciprocating engines, and Superior Air Parts, Inc. IO-360 series reciprocating engines with certain Precision Airmotive LLC RSA-5 and RSA-10 series fuel injection servos.
Background
This emergency AD results from eighteen* reports of fuel injection servo plugs, part number (P/N) 383493, that had loosened or completely backed out of the threaded plug hole on the regulator cover of the fuel injection servo. These servo plugs were installed with servo plug gasket, P/N 365533, under the plug hex-head. Precision Airmotive LLC investigated and determined that servo plug gasket, P/N 365533, can shrink from engine heat, causing the plug to lose torque against the servo regulator cover, allowing the plug to vibrate out. The threads on the plugs were also found damaged. Servo plug gaskets, P/N 365533, installed on RSA-5 and RSA-10 series fuel injection servos since August 22, 2006, are made of a different material than the previous gasket part number used. This condition, if not corrected, could result in a substantial loss of engine power and subsequent loss of control of the airplane."

This affects all Cessna 182T aircraft (also 172/206 and other makes built from 2006 onwards). Cessna have just issued the SB. I have just returned from the airfield after inspecting mine (rock solid 
)
It a very easy inspection on the 182 - open port side cowling and below the engine is the Fuel Servo and aforementioned hex plug! Cessna have amended the service schedule to include its inspection every 50hrs.
The SB states they are awaiting a long term fix...
PS. The SB only mentions 2 previous problems.

This may also affect some aircraft on the LAA permit to fly.
