Fix For Flap Vane Fouling

— Jason Behrens

Is one or both of your inboard flap vanes fouling on the flap drive torque shaft of your Hawker? This condition is indicated by chafing on the underside of the inboard flap vanes where they pass too close over the drive shafts. Recently we have noted this condition on two aircraft. Raytheon has a repair that has been around a few years that is not in the Maintenance Manual or SRM. You can obtain the repair from Raytheon Technical Support. Just ask for Repair Instruction Letter No. RIL-25-WF46, titled Rectification of Inner Flap Vane Fouling on Torque Shaft. The RIL gives provisions to adjust the vane’s position up by fabricating a new outboard attach bracket and relocating mount holes, therefore moving the vane up away from the torque shaft. You can acheive further adjustment by placing additional shims under the bevel gear box and installing longer mount bolts as needed. Try the shimming action first to see if this gives you the required clearance as we have had good luck with shimming only.

Landing Gear Life Limited Parts

— Chris Gress

More and more Hawker 400 through 700 operators are unable to find the total landing documentation for the “life limited parts” inside their landing gear. It seems that years ago (in the 1980s & 1990s) some overhaul shops did not mention the life limited parts at the time of the overhaul. In many cases, used and reconditioned life limited parts were installed, but the landings on that part was not documented. Several of these companies have since gone out of business, stopped overhauling Hawker gear or can’t find records that old.

If your landing gear will need to be overhauled in the next year or two, and the last overhaul was in the 80s or 90s, we recommend that you locate the previous landing gear’s “return to service maintenance release & work order data” from those decades.

High service activity levels in the industry are making it more and more difficult in securing your first or preferred choice of service centers and schedule.We have some tips that will help you avoid some of the pitfalls when planning your next event.

First and foremost, three months is not enough! With only three months lead time; you are not likely to get your first choice of schedule and facility. Plan at least six months in advance for an average workscope–twelve to eighteen months in advance for a large workscope. Just a few advantages of advance planning are: getting your first choice of facility and schedule; obtaining the best downtime; having plenty of time for planning and ordering parts and materials.
