a main gear is around $296,000
USD. The nose gear for a Q 400 is
about $1.2 million USD and the
main gear is $998,000 USD. In one
instance, "Av-Reps was able to
get Transport Canada approval to
ream a steering manifold body on
a DCH-8 and save the customer
about $6,000 USD."
I asked if Av-Reps could offer
any tips or advice to help operators extend the service lives of
landing gears and reduce overhaul
costs. The company suggested
several practices that could save
time and money. "Keep the oleo
strut serviced, follow the work
cards, and keep all the gear links
lubricated; this makes a significant
difference in the overhaul bill of
work. Inspect the gear bushing
and gland nuts to ensure that the
protective sealant is intact. Keep
all chrome surfaces on struts and
actuators clean and inspect for
FOD damage."
After the interview with
Av-Reps it appears there is no big
mystery about aircraft landing
gear systems. The explanation is
practical aeronautical engineering,
quality materials, modern manufacturing processes, and maintenance. As AMTs we should strive
to be as reliable as these landing
gears and follow those work cards.
We know it's all about preventative maintenance! AMT
