Block 9: PC signature I have personally inspected this A/C IAW the applicable MRC/checklists. Any discrepancies noted have been entered on a work order. CNAF 4790/38(preflight/daily/TA/postflight mx record)
Block 10: Certification of safe for flight condition by personnel authorized by the commanding officer to release the A/C SFF. (Maintenance Material Control Officer, Maintenance Control Officer) others in MMP
Block 11: I have reviewed the discrepancy reports of the 10 previous flights, ensured proper filing of weight and balance data and accept this A/C safe for flight.
RBA
Ready Base Aircraft Aircraft is FMC and is ready to fly? Mx has been completed and should be good to go but it hasn’t been tested.

Air card, Pen, and Pencil
Conditional
Unscheduled events required because of a specific over limit condition or admin requirement for an inspection. Engine water wash because of overwater flight. Post Terf inspection after unprepared landings. Post Dip after Dip Sortie. Swap out stab actuator, FCF?
Pre/Post Depot Level Inspection
Prior to and after reporting custodian sends/receives an A/C to/from on-site standard and special rework.

C: Controllability
D: AFCS
Special
Scheduled with a prescribed interval other than a daily or phase. (7, 14, 28 day or 60hr) Some MRCs are cut in half when underway to aid in corrosion prevention. (Fresh water washdown every 7 days underway instead of 14) 546 day is the worst special (takes apprx 5days)
Fresh Water wash down Underway
Waterwash is every 14 days normally but it’s every 7 days underway.
Daily
Inspects for defects to greater depth than the TA. Always completed before the TA. Valid for 72 hours after completion provided no flight or mx other than servicing occurs. May be flown for 24 hours beginning at rotor engagement of the first flight. 24 hours can not exceed the 72 hour expiration of the daily unless the expiration occurs during a mission.
*Mx Control will determine if a daily need to be completed again depending on the mx performed.
*24 hours only starts at rotor engagement of the first flight that gets airborne. Penalty turns don’t count.
*An AC line is considered one flight so as long as the first launch is before the 24 hour period expires all following hotseats are considered part of the mission.
*CO may authorize PIC to to perform pilot inspection, ensure servicing requirements accomplished and sign A Sheet in certification block when away from home without qualified mx personnel for periods not exceeding 72 hours. Accomplishing this rather than completing daily, TA and fuel sampling is sufficient for SFF.
Transfer Inspection
Shall be performed when a reporting custodian transfers an ATO A/C to an offsite FRC/commercial rework facility or to another operational unit. E.g. we send an aircraft to HSM-41
Phase Inspection
Done sequentially at specified intervals (every 200+/- 10%)
D profile is the worst because of the work on the main rotor head. We only have one blade in the PUK and it could down a bird. (Also other parts…)
A Phase: Main Landing Gear (on jacks) tail rotor, ABCD, AC, A cards
B Phase: take one blade out and spindle apart, XSMN Oil Cooler ABCD, BD, B cards
C Phase: Tail Rotor ABCD, AC, C cards
D Phase: MRH, Spindles ABCD, BD, D cards PMI is every 36 months, Depot Level Mx? FRC (is I Level Mx?), replacing an engine.
PMC vs PMCS vs PMCM
PMC is Partially Mission Capable according to the codes found in the MESM.
PMCS means the aircraft is PMC awaiting a part from supply.
PMCM means the aircraft is PMC awaiting the maintenance to be completed.
Turnaround
Checks integrity, servicing and degradations Valid for 24 hours from completion (based off fuel sampling time) unless flown and AC is shutdown and there is a HAC turnover or maintenance other than servicing is completed. (Unless shutdown is scheduled, CATM download)
*If the HAC turnover occurs during a hotseat the TA is postponed. If the A/C is shutdown but the HAC remains the same our SOP says the turnaround may be postponed as long as the period between startup and shutdown does not exceed two hours.
*Mx Control will determine if a TA need to be completed again depending on the mx performed.
*CO may authorize PIC to to perform pilot inspection, ensure servicing requirements accomplished and sign A Sheet in certification block when away from home without qualified mx personnel for periods not exceeding 72 hours. Accomplishing this rather than completing daily, TA and fuel sampling is sufficient for SFF.
*TA is not required between repetitive flight evolutions interspersed with ground periods such as PMC stops, hotseats, hot refueling or short stops for adjustments during FCFs.
Types of Maintenance
O level: Organizational Level
I level: Intermediate Level (AIMD)
D Level: Depot Level FRC vs PMI
AMSRR and AMCR
Aircraft Material Status Readiness Report
Aircraft Material Condition Report = Tracks hours, Downing Gripes, and Readiness
Zonal Inspection
General Inspection of a specific area. Swap out part, no TA/Daily but zonal?
IW on a MAF
In Work Period of time that the helicopter was being worked on. Sort of like a time card for checking in and out of work.
