Beech: A36; Loose Rudder Pedals; ATA 2720
A repair station technician writes, “Upon investigating a loose rudder pedal (discrepancy), the (controls) were
disassembled. (We found) that the shaft had been double-drilled with the holes overlapping. This aircraft was
certificated in January of 2002; it now has 1,015.4 hours time in service.”

Beech: G18; Wing Spar Corrosion; ATA 5711
An unknown submitter states, “This defect (describes) severe corrosion in the L/H spar tube at wing station 90. The probable cause is exposure to moisture over an extended period of time. My recommendation to prevent recurrence would be to seal and fill (the spar tubes) with linseed oil. A further recommendation would be to (perform) visual and dye penetrant inspections of this area at 25-hour intervals up to the first 100 hours. If no fatigue cracks are noted, extend the inspections to every 100 hours — or each year — whichever occurs first.”
