5-20-06 - 100- HOUR INSPECTION (or ANNUAL
INSPECTIONS)
(Refer to Fig. 5- 1)
The 100- hour (or annual) inspection is a thorough,
searching inspection of the entire aircraft. Preparation
for the inspection includes the removal of all fuselage,
wing, and empennage inspection doors, cover plates,
and fairings at all systems attach, hinge, and bearing
locations (including wing and empennage to fuselage
mating points). Remove pilots & co- pilots seats, lower
LH & RH side interior panels to gain access to fuel tank
INBD ribs & s
ensor locations and tubular structure. Op-
erating limit replacements (See Section 5-10-01) and
special testing of components is to be included at this
interval, when applicable. Comply with applicable FAA
Directives, Airworthines
s Directives Notes (AD’s), and
applicable Mooney or Vendor mandatory Service Bul-
letins and Instructions. Check for aircraft conformance
to FAA Spec
ification 2A3 for M20V Model aircraft.
Recommended 100- hour/annual and special inspec-
tion requirements are outlined in the following para-
graphs:
1. ENGINE INSPECTION. Prior to the inspection, re-
move engine cowling and propeller spinner. Wash en-
gine and engine compartment down. Then perform an
engine runup in accord with 100 hour procedure rec-
ommended in CMI Engine Maintenance and Operators
Manual. To verify correction of malfunctions and abnor-
malities, perform a second runup and flight test after
the 100- hour/annual inspection engine set- up.
A. Complete a differential (hot engine) compres-
sion check (Ref. CMI SB M84- 15 or current rev.): clean
and gap or replace spark plugs (.016/.021 both Cham-
pion fine wire and thick electrode), also refer to
manufacturer for proper specifications.
B. Inspect engine for evidence of fuel and oil leak-
age. Inspect oil cooler. Inspect oil and fuel hoses for
condition and security.
C. Drain engine oil sump; remove, clean, and in-
spect oil suction screens; reinstall and safety. Remove
full- flow oil filter cartridge; replace with new cartridge
and safety. It is recommended that old filter be opened
up to check for metal particles & foreign matter. Check
crank case breather lines for obstruction. Safety wire oil
filter installation.
D. Refill engine oil sump with the proper type,
grade, and quantity of lubricating oil.
E. Inspect fuel injector, fuel line connections for se-
curity and condition and fuel nozzles (Ref CMI SB).
F. Remove and inspect gascolator strainer, rein-
stall strainer. Inspect fuel lines and connections: pres-
sure check fuel system with mixture control at IDLE
CUTOFF and BOOST PUMP “ON”.
G. Inspect all air ducting and connections in cabin
heating air systems for leaks. Leak check all exhaust/
manifold connections and engine exhaust manifolds
(SEEPara.5-20-06,1,Q,R&Sbelow).
H. Remove and clean induction air filter (replace at
500 Hrs or annually). Inspect alternate air door and
magnet for security and operation. Inspect all air duct-
ing and connections in the induction air system for
leaks.
I. Check magnetos for grounding and synchroniza-
tion (timing to engine); inspect magneto points for con-
dition, clearance, and internal timing. Inspect distribu-
tor block for erosion and cracks. Inspect cam follower
felt for proper lubrication, and remove excessive oil
from breaker compartment. At 500 hours inspect mag-
neto per CMI/BENDIX magneto maintenance manual.
Repair or replace components, if required.
J. Inspect baffles for secure anchorage, cracks,
holes, deformation, and for close fit around cylinders.
Inspect cylinders for burned paint and cracked and bro-
ken fins. Inspect baffle sealant.
K. Inspect accessory case, starter, alternator, fire-
wall and fittings for security and damage.
L. Inspect tubular engine mount for cracks, dam-
age and corrosion; inspect all bolts and rubber isolation
mounts for security and condition.
M. Inspect engine and propeller controls for free
operation, full travel, proper connection (security) of
