AIRFRAME TECHNOLOGY
a layer of high-magnitude compression deeper than
the surface damage deters SCC and fatigue crack initiation, from undetectable micro cracking up to visible damage from FOD or corrosion.
Unlike traditional surface treatments like shot
peening and deep rolling, LPB provides protection
with very little cold work. This makes the compressive layer stable under either thermal exposure following plating or mechanical overload in service. The
result is a mirror-like surface finish that is less chemically active than a highly cold worked surface.
Implementing solutions
The process mitigates cracking in a single maintenance cycle, and never requires reapplication. Basic
CNC machines like mills, lathes, and robots are
used making integration into production easy during either manufacture or by an MRO specializing in
landing gear repair and overhaul. Technicians aren't
required to learn specialized foreign equipment or be
certified in any special way. Robotic LPB systems can
be used in a hangar environment, allowing landing
gear components to be processed without removal
from the aircraft and increasing time in service.
Regulation and acceptance
LPB is FAA accepted for repair and alteration of both
structural and engine aircraft components. Lambda
has teamed with Delta TechOps to offer the process
to the commercial fleet. Currently, Delta TechOps and
Lambda are working to implement LPB as an A.D.
Alternate Means of Compliance (AMOC) for landing gear that normally require expensive frequent
inspections or replacement. The process is not a PMA
replacement. All LPB treated parts remain 100 percent original OEM pieces.

Summary
LPB can dramatically improve the damage tolerance
of landing gear and mitigate failure from SCC. Parts
can withstand larger loads with longer intervals
between inspections, saving time and money on
maintenance operations. AMT
