Maintenance Requirements Determination or MRD is a fundamental part of Integrated Logistic Support.

MRD is the umbrella term for: Failure Modes Effects and Criticality Analysis (FMECA), Reliability Centred Maintenance (RCM), Maintenance Task Analysis (MTA) and Level of Repair Analysis (LORA).
FMEA, RCM, and MTA are also referred to as Maintenance Engineering Analysis (MEA).

Corrective Maintenance is the repair of a piece of equipment to return it to a serviceable condition.
It is usually:

  • unplanned and
  • performed upon the failure of the equipment.

Corrective maintenance does not include:

  • planned maintenance such as oil or filter changes,
  • hour/ time based maintenance or overhauls.

Preventive Maintenance is the servicing of a piece of equipment to maintain it in an operable condition that allows it to meet the specifications of its operational requirements.

It is usually:

  • planned and
  • performed before the failure of the equipment,
  • performed as insurance against equipment failure.

Preventive maintenance includes:

  • planned maintenance such as oil or filter changes,
  • hour/ time (calendar days / months/ years) based maintenance or overhauls.
    • eg monthly, 3 monthly, 6 monthly, 12 monthly, 250 hrs, 500 hrs, 2000 hrs, 6000 hrs

It is important to understand that the intention of preventive maintenance is to prolong the operating life of the equipment by replacing components before they fail, however preventive maintenance cannot stop failure  completely.
