Manufacturer Adds 1000 To Number Of Affected Assemblies
Superior Air Parts has
added 1000 to the number of cylinder assemblies affected by the
recall first announced in a September service bulletin.
The company says cylinder barrels from assemblies identified by
Service Bulletin B06-01 D weren't properly hardened to
specification which could result in fatigue cracking of the
cylinder head.
Superior fears propagating cracks may lead to head and/or barrel
separation and loss of power in flight. SB B06-01 D requires the
removal of the affected assemblies manufactured between April and
November 2005.
According to the SB, affected cylinders must be replaced before
reaching 150 hours time in service (TIS). If an affected cylinder
has exceeded 150 hours TIS then it must be replaced within ten
hours.
The SB lists affected engines as follows:
Teledyne Continental Motors Engines:
- O-470-G, -K, -L, -M, -P, -R, -S, -U;
IO-470-C, -D, -E, -F,-G,-H, -L, -M, -N, -P, -R,
