criteria method.
For example, an AH-64 main rotor P/C link inspection
is due every 14 days or 10 flight hours, if the aircraft had 1709
hours when the last inspection was completed on 22 May 1997 the next
inspection is due at 1719 hours or on 5 June 1997, whichever comes
first.
Using the plus or minus 10 percent tolerance window not to
exceed 5 hours or 30 days, the next inspection is due between 4 June
and 6 June 1997 or between 1718 and 1720 aircraft hours, whichever
comes first. When developing the due time/date of the next inspection
each side of the dual requirement is computed separately by using the
appropriate instructions in paragraph 2-10.a. and 2-10.b.
If one
element of the dual criteria inspection is within a tolerance window
the rules for tolerance windows only effect that element.
The side
not in the tolerance window is computed by adding the inspection
frequency to the current hours or date.
2-11. Non-recurring Special Inspections.
The -23 TM for all standard
aircraft contains special instructions for aircraft that have been
subjected to an unusual event.
These inspections are non-recurring
special inspections and are contingent upon certain conditions or
incidents.
For example; aircraft flown in the rain, subjected to salt
water spray, struck by lightning, hard landing, sudden stop/reduction,
overspeed, or any type of accident/incident. All non-recurring
special inspections must be accomplished before the next flight.
Preflight Inspection.
The preflight inspection is a
combination of flight preparedness checks and inspections accomplishes
before a flight.
The preflight will be completed per the operator's
manual
and operators and crew members checklist (TM-CL).
The
preflight also includes a review of the aircraft logbook forms and
records per DA Pamphlet 738-751.
The review is to determine the
aircraft status, to ensure that the symbol in the status block of the
DA Form 2408-13 shows the current condition of the aircraft, that no
inspections or checks are overdue, and the aircraft is safe to fly.
2-13. Thru-flight Inspection.
The thru-flight inspection is a

accomplished between flights when a turnaround mission or a
continuation flight is scheduled during a mission day.
Thru-flight
