Citations dogged by control problems
It has not been a good summer for the Cessna Citation 650 or 525.

It has not been a good summer for the Cessna Citation 650 or 525. Last month, owners of the Cessna 650 Citation VII learned of a proposed AD (Docket No. 2002-NM-332-AD) that would require repetitive replacement of the horizontal stabilizer primary trim-actuator assembly with a repaired assembly. According to the AD, the move is necessary to prevent uncommanded movement of the horizontal stabilizer that could result in reduced controllability of the airplane.

The AD counters an existing Cessna Service Bulletin recommending a one-time replacement. The FAA is proposing a replacement interval not to exceed 18 months and estimates the cost to each of the 285 U.S.-registered aircraft to be $2,276 per replacement cycle, with Cessna providing the parts at no cost to the owner. The FAA is accepting comments on the proposal until September 22.
