Horizontal stabilisers - Cessna 200 series
Single piston engine 200 series Cessna aircraft that are older than 15 years since date of manufacture.
There have been a number of Service Difficult Reports (SDR) regarding spar (and attachment) cracking on Cessna 210 aircraft horizontal stabilizers. Aircraft featured in the reports have a TTIS greater than 9,500 hours and covered a range of different 210 models.
Although the exact source of the cracking is unknown, one plausible cause could be incorrect ground handling techniques such as putting weight on the tailplane to lift the nose wheel off the ground for aircraft manoeuvring or maintenance. This practice places severe stress on the structural components of the empennage and is not condoned by either the manufacturer or CASA as an approved procedure.
Maintenance personnel should pay particular attention while inspecting this critically structural area. In some circumstances further disassembly may be required to satisfy the LAME of the integrity of the structure. Further disassembly should only be attempted if the workshop has the appropriate tooling, jigs and expertise to undertake the task. Also, all personnel should be educated in the appropriate ground handling techniques utilised for the aircraft.
Report all defects to CASA as required by CAR 52.
