Aircraft Maintenance Technology - 41

Bolton said that he sees composite blades
as taking a stronger and stronger hold in
the industry in the coming years.
"In recent years we have seen a move
toward all composite constructions.
Traditionally even blades considered as

composite still had a metallic structural
spar, but with the advances in composite
manufacturing techniques the most modern designs now incorporate composite
spars," he said.

AVIATION FABRICATORS

Bolton described the difference between
repairing composite and legacy blades.
"The metal blades are comprised of a
structural spar with numerous unique
bonded pockets to provide the airfoil shape;
we find the common areas requiring maintenance to be pocket replacements and
leading edge abrasion strip replacement,"
Bolton said. "Fortunately, we've developed
PMA replacement pockets to support these
legacy aircraft that still have years of productive service.
"The composite blades are also built
around a structural spar but with a nomex
honeycomb core and fiberglass skin for
the airfoil and strength. Repairs here primarily center around composite skin and
honeycomb damage repair as well as lead
edge abrasion strip and sheath repair and
replacement."
ABS carries out all composite repairs in
the environmentally controlled area of their
facility, following complete inspection of
the blade, Bolton noted, and generally, there
will be a mix of fiber glass skin and honeycomb repairs both requiring different repair
techniques - either surface patch or scarf.
"Once the area is prepared and the repair
materials installed, ABS uses a combination
of custom and industry standard equipment to apply the requisite heat, pressure
or vacuum for the controlled curing process.
Once cured, the blade is completed and sent
for further inspection, final paint and static
balance," he continued.

The World Leader
in General Aviation Seat Recline Cylinder Overhauls

AvFab pioneered the quick-turn overhaul of seat recline cylinders, performing hundreds of
these FAA-approved repairs every month. Your P.L. Porter, Enidine, Roton and Sicma cylinders
can be made like new at a fraction of the cost of replacement. Plus, your AvFab-repaired
cylinder comes with FAA 8130-3 or EASA Form 1 Dual Release Return to Service
documentation and it has the same warranty as a new cylinder. Turn times are two to
four days. If exchange units are available, you may even be able to have parts the next day.

Recline and relax. We've got your back.
