The scope of a 100 hour and an annual inspection are the
same, the difference is that a 100 hour can be done by any
A&P and it is only recorded in tie logbook [maintenance
record], while an annual must be done by an AI.

Appendix D to Part 43-Scope and Detail of Items (as
Applicable to the Particular Aircraft) To Be Included in
Annual and 100-Hour Inspections

evidence of failure, and defective or insecure attachment of
fittings.

(2) Systems and components-for improper installation,
apparent defects, and unsatisfactory operation.

(1) Generally-for uncleanliness and loose equipment that
might foul the controls.

(2) Seats and safety belts-for poor condition and apparent
defects.

(3) Windows and windshields-for deterioration and breakage.

(4) Instruments-for poor condition, mounting, marking, and
(where practicable) improper operation.

(5) Flight and engine controls-for improper installation and
improper operation.

(6) Batteries-for improper installation and improper charge.

(7) All systems-for improper installation, poor general
condition, apparent and obvious defects, and insecurity of
attachment.

(d) Each person performing an annual or 100-hour inspection

and nacelle group as follows:

(1) Engine section-for visual evidence of excessive oil,
fuel, or hydraulic leaks, and sources of such leaks.

(2) Studs and nuts-for improper torquing and obvious
defects.

(3) Internal engine-for cylinder compression and for metal
particles or foreign matter on screens and sump drain plugs.
If there is weak cylinder compression, for improper internal
condition and improper internal tolerances.

(4) Engine mount-for cracks, looseness of mounting, and
looseness of engine to mount.

(5) Flexible vibration dampeners-for poor condition and
deterioration.

(6) Engine controls-for defects, improper travel, and
improper safetying.

(7) Lines, hoses, and clamps-for leaks, improper condition
and looseness.

(8) Exhaust stacks-for cracks, defects, and improper
attachment.

(9) Accessories-for apparent defects in security of
mounting.

(10) All systems-for improper installation, poor general
condition, defects, and insecure attachment.

(11) Cowling-for cracks, and defects.

(e) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) the following components of
the landing gear group:

(1) All units-for poor condition and insecurity of
attachment.

(2) Shock absorbing devices-for improper oleo fluid level.

(3) Linkages, trusses, and members-for undue or excessive
wear fatigue, and distortion.

(4) Retracting and locking mechanism-for improper operation.

(5) Hydraulic lines-for leakage.

(6) Electrical system-for chafing and improper operation of
switches.

(7) Wheels-for cracks, defects, and condition of bearings.

(8) Tires-for wear and cuts.

(9) Brakes-for improper adjustment.

(10) Floats and skis-for insecure attachment and obvious or
apparent defects.

(f) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) all components of the wing
and center section assembly for poor general condition,
fabric or skin deterioration, distortion, evidence of
failure, and insecurity of attachment.

(g) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) all components and systems
that make up the complete empennage assembly for poor
general condition, fabric or skin deterioration, distortion,
evidence of failure, insecure attachment, improper component
installation, and improper component operation.

(h) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) the following components of
the propeller group:

(1) Propeller assembly-for cracks, nicks, binds, and oil
leakage.

(2) Bolts-for improper torquing and lack of safetying.

(3) Anti-icing devices-for improper operations and obvious
defects.

(4) Control mechanisms-for improper operation, insecure
mounting, and restricted travel.

(i) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) the following components of
the radio group:

(1) Radio and electronic equipment-for improper installation
and insecure mounting.

(2) Wiring and conduits-for improper routing, insecure
mounting, and obvious defects.

(3) Bonding and shielding-for improper installation and poor
condition.

(4) Antenna including trailing antenna-for poor condition,
insecure mounting, and improper operation.

(j) Each person performing an annual or 100-hour inspection
shall inspect (where applicable) each installed
miscellaneous item that is not otherwise covered by this
listing for improper installation and improper operation.
