of engines, APUs and landing gear.
Engines are generally reunited with
aircraft. APUs and landing gear may
not have to be, but it is desirable.
Engines require at least borescope
inspection, maximum power assur-
ance (MPA) runs and tests of exhaust
gas temperature (EGT). Return checks
on airframes can include re-inspection
of structural repairs, cosmetic fi xes,
overhauling seating and repainting.
“These things can take an extra week,
or $100,000,” Clarke notes. “Planning
for them is critical.”
Components generally need to have
24 months left to overhaul, and certi-
fi cation tags. “If you lost the tag, you
must overhaul or replace the compo-
nent,” Clarke says.
Clarke sees programs like CFM’s
PML as increasingly prevalent, noting
that Rolls-Royce of ers a similar prod-

due to bilateral agreements. Elsewhere,
dif erences persist. Even in the U.S.,
some primary maintenance inspectors
still insist on “dirty fi ngerprints,” Denis
notes. Fortunately, “the world is follow-
ing EASA.”
That should mean XML documenta-
tion according to ASD standards. And
new aircraft should set the pace. Denis
says most OEMs are going this way for
their new models. The engine makers
have adopted the new ASD standards.
Airbus did not for the A380, but will for
the A350. Bombardier’s CSeries will,
as will the Mitsubishi Regional Jet and,
probably, Embraer’s E2 jets. The Boe-
ing 787 is not on the new standards,
but Denis thinks this may change when
Boeing starts delivery of its KC-46
tanker, which will require the latest
ASD standards.
If Boeing joins the ASD movement,
that also may give standardization a
critical push. c
