CHP Grounds Cessna Fleet
The California Highway Patrol (CHP) decided to ground all 14 of its Cessna Turbo 206 aircraft after one made an
emergency landing. Last week, CHP Pilot John McDermott landed his plane safely after experiencing a total engine
failure at 9,000 feet en route from Redding to Clear Lake, Calif. The Cessna Turbo 206 that he was flying was only a
few weeks old and one of 14 acquired by the CHP last month. Local media quoted agency officials as indicating that
they had found a crack in the aircraft's engine case. The crack, found on both halves of the Lycoming TIO-540
engine, was described by CHP officials as a fault-line that covered "one third the circumference of the block."
If that wasn't enough, the FAA has released a Special Airworthiness Information Bulletin (SAIB) for Lycoming
TIO-540 engines, which deals with main a bearing delamination that leads to total engine seizure. The SAIB was
issued August 16 and affects engines constructed with front main bearings installed after August 24, 2000.
According to some sources, the CHP is in the process of deciding whether to send the airplanes back, and not
accepting delivery of the remaining 20 on order. For now, the aircraft remain grounded. For those of you who think that this is your "ticket" to speed along the state's highways,
think again. The CHP announced that they still have at least one Cessna 185 flying over the I-5 corridor.
