The first character (alpha) is documented in NALCOMIS OOMA. The second and third characters (numeric) are computer generated from the first two positions of the WUC/UNS

A: FMC

B:

C: Command Control Communications Systems

D: Hawklink Capability

E: SUW Mission

F: ASW Mission

G: Ordnance System

H: SurvivabilitySystem

Special

A

Scheduled on a prescribed recurring interval other than daily, phase, major engine, or standard depot rework. (7, 14, 28 day or 60hr)

+- 3 days/+- 10% hours

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)

Q

Daily

A

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.

*24 hours only starts at rotor engagement of the first flight that gets airborne. Penalty turns don’t count.

*When required for a cross-country flight, or when aircraft must be operated away from home base without qualified maintenance support for periods not exceeding 72 hours, the CO may authorize the pilot-in-command to conduct pilot inspection in lieu of a Daily inspection, certify servicing requirements are accomplished, and sign the A-sheet. On a case-by-case basis, Wings and MAGs may authorize an additional 24 hours (maximum of 96 hours), due to operational necessity. Accomplishing this rather than completing daily, TA and fuel sampling is sufficient for SFF.

Q

Phase Inspection

A

Done sequentially at specified intervals (every 200+/- 10%).. All will require at minimum BC FCF profiles. -

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.

Q

PMC vs PMCS vs PMCM

A

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.

Q

Turnaround

A

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.

*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.

Q

Types of Maintenance

A

O level: Organizational Level
-O-level maintenance is basic maintenance performed by an activity on its assigned aircraft and equipment. O-level maintenance is organized to achieve quick turnaround of aircraft and equipment in order to optimize operational availability (Squadron)

I level: Intermediate Level (AIMD)
-The primary focus of I-level maintenance is to produce ready-for-issue (RFI) parts and ready-for-use (RFU) support equipment in sufficient quantities to support aircraft operations. (FRC)

D Level: Depot Level FRC vs PMI
-D-level maintenance and rework is performed by designated depot activities on aircraft, equipment and material requiring overhaul, upgrading, or rebuilding of parts, assemblies, subassemblies, and end items, including manufacture, modification, testing, and reclamation of parts. (Civilians)
