Does your Chieftain have broken ribs?
Look at Wing Station 39.5.


Problem:
If you gear retraction actuator has been or is now improperly rigged, it will cause the hydraulic fittings on your dual brake calipers to beat the Wing Rib at station 39.5 into little pieces. Even when properly rigged to the Piper spec., the fitting clearance is minimal and damage can still occur if your retraction bumpers are worn out. This damage appears to be common to all dual caliper equipped PA-31-350/T1020's we'be inspected.

Solution #1:
Piper fix - requires the removal and replacement of both 39.5 Ribs at a cost of approximately $750 for parts and 20+ man-hours to reomove, replace, replumb and rerig. Not a real attractive solution.

		Solution #2: BLR "Quick Fix" - requries installation of our stainless steel Rib bridge, which allows the main gear to complete the retraction cycle by providing adequate clearance for the hydraulic
fittings, while maintaining wing station loads at a cost of $695 (Super Chief II owners $395) for parts and 4 man-hours, no plumbing or rigging required. It's your time and money, you decide!
