Excellence Program
Lean Philosophy - Encompasses 100% of OGMA Employees
Kaizen and Continuous Improvement Methodology
Eliminate waste from the Maintenance Process
– Eliminate unnecessary tasks
– Eliminate unnecessary efforts for necessary tasks
– Streamlining Process
LEAN ON C-130
MAINTENANCE
Streamlining Process
• Mapping out the maintenance
process
step-by-step
• Highlight the bottlenecks
• Look for root causes
• Search for the
effective solutions

MAINTENANCE
Time Observation
(Spaguetti Diagram)
• Watch the operator
performing his work
• Draw the operator’s path on
the hangar, and record the
cycle times for each
maintenance step

Elevator Trim Tab Hinge Fitting
• Severe wear of elevator trim tab
attaching
bolts
(P/N
AN177CH16) was found in
some C130 aircraft operators
• Bolts
were
retained
for
investigation and all fleet was
inspected
Elevator Trim Tab Hinge Fitting
• In-flight rupture of LH elevator trim tab hinge fitting
• Bolts found with severe wear
PROBABLE CAUSES:
• Applied torque of horn fitting joint assemblies
• Different tapers on bushings
Elevator Trim Tab Hinge Fitting
PROBABLE CAUSES:
1) Applied torque of horn fitting joint assembly
• Maintenance manuals do not clearly indicate the correct torque value for
the assembly
• LM clarified that Torque on nut P/N73781CM720 should be 205+/-35
in.lbs per LM Aero Process Specification 0581
Elevator Trim Tab Hinge Fitting
PROBABLE CAUSES:
2) Different tapers on bushings
• Correct bushings must have an angle of 68º.
Some were found to be 79º!
• If wrong set is used (different tapers), the
contact area between bushings will be limited
and will cause fast wear. This wear will cause
play in the join and the torque is no longer
effective causing abnormal wear by friction of
bolts.
Replace both new cone bushings at the same time, not
individually, or the entire horn assembly (3326589-1)

Rudder Booster Lever Failure
• A C130 operator reported an in air
mishap, resulting in the loss of the
Rudder Booster System.
• Inspection of Rudder Booster
Assembly found Lever Assembly
P/N 354648-1 (sub assembly of
rudder booster P/N 372021-7)
ruptured in four places
• Defective part under investigation
• Similar events known by USAF,
European operators and LM.
Rudder Booster Lever Failure
PROBABLE CAUSES:
• This type of failure is found after the aircraft
has been exposed to sustained High Winds
while the booster and utility hydraulic
systems were not adequately pressurized and
the flight controls cycled to use the snubbing
effect
in
the
boost
packs.
• Use Card No SP-283 is recommended to
inspect for damage any time the aircraft has
been subjected to High Winds

Center Wing
FWD Upper Spar Cap
• During 2013 “C” checks inspection of
two different operators, a layer of stress
corrosion was found on center wing FWD
upper spar cap WS 72 LH.
- C130H, 30 year insp, EBH 20,878
- C130H, 30 year insp, EBH 19,496
• If damage enters large block of material
on LS shape, no repair is possible
• Use of Card No SP-311 is recommended
but initial inspection is set to 30,000
EBH!
