What is LORA Training?

Level of Repair Analysis (LORA) training teaches an analytic method used to determine where (level or location), and how the equipment is best repaired, replaced, and/or discarded based on cost and operational readiness requirements.

LORA applies to all equipment life cycle phases including systems acquisition, modification, and research and development programs.

Applicable industries include, but are not limited to, Aerospace & Defense, Manufacturing, Pharmaceutical, Food Processing, Chemical Processing, Mining, Facilities, Weapon Systems, Agriculture, Alternative Energy, Energy Distribution, and Power Generation.

The Goal

Level of Repair Analysis (LORA) aims to control and reduce life-cycle costs through optimized maintenance, repair, and obsolescence scheduling. LORA attempts to determine how an acquisition will be supported and suggests who shall make which repairs, under what circumstances and where the repairs will take place.

LORA helps supportability and logistics engineers plan for optimal repair decisions in complex environments with tiered layers of assemblies and sub-assemblies. Considerations for Level of Repair Analysis (LORA) include cost of equipment to analyze component operations/repairs, the skill level of staff in assessing and repairing equipment, warehousing of parts, and operational facilities to complete repairs and testing. The LORA process sometimes finds that replacing a part often costs hundreds of times that amount when the full costs of repair are calculated making equipment far costlier to repair than discard.

Learn the engineering principles used at reliable, high-performance plants for the life cycle of physical assets in the military, municipal and commercial sectors. Join the LORA certified technicians and physical asset owners in implementing and improving cost-effective maintenance programs using a logical and comprehensive SAE-AS 1390 compliant LORA process.

SAE-AS 1390 (Society of Automotive Engineers)

The technical standard: Level of Repair Analysis (LORA)

AS 1390 establishes the standard of requirements of the activities involved in the performance of LORA during the life cycle of equipment. Completing the activities in a logical order and iterative fashion comprises the LORA process.

Cost models calculate all the possible iterations of maintenance, repair, and replace options and determine an optimal cost solution for each case.

LORA is performed in two steps:

  • Establish noneconomic decision criteria to make the initial support decisions
  • Evaluate an economic model to determine the most cost-effective alternative to provide support for the system

The LORA system identifies options for location of maintenance including combinations of levels to achieve maximum cost-effectiveness.

Organizational or O-level maintenance is indicated to take place at the organizational unit level and prioritizes quick turn-around for maximum operational availability. Generally O-level consists of Repair-in-place (RIP) procedures using spare inventory components when failed components can be removed and replaced (R&R).

Intermediate or I-level maintenance requires a backshop or other off-site operating base. Repairs are more specialized and usually require more diagnostic equipment. Spare parts are known as bench stack at the intermediate level.

Depot or D-level maintenance occurs at specialized shops or original equipment manufacturer (OEM) facilities. Equipment overhauls and re-manufacturing is done at the D-level.

The LORA system indicates, first, “where” repairs take place and may be a tiered system.

The outcome is a systemic maintenance program that prioritizes up-time and efficiency at the lowest cost. Many times LORA sets a price at which units will be discarded and replaced versus repaired.

What You Will Learn:

  • Economic LORA evaluation - the process to identify the most cost - effective maintenance plan for all LORA candidate equipment
  • Level of Repair Analysis - the method by which maintenance levels are established based on limits obtained through evaluation of economic, non - economic, and operational readiness qualifications
  • Creation of the LORA candidates list - compiling lists of all LORA program components
  • Noneconomic LORA evaluation - identifying preemptive considerations which override cost factors
  • Ascertaining risk - tools to measure future uncertainty defined by cost and performance
  • Sensitivity evaluation - determining the extent to which model parameter estimates fluctuate
  • Maintenance planning - and its relevance to LORA
  • Reliability engineering - and its impact to LORA
  • Maintainability engineering
  • Provisioning - and life-cycle costs based on LORA decisions


Level of Repair Analysis (LORA) is a comprehensive introductory course covering the process of LORA, its benefits, limitations and optimal implementation. The preliminary course introduces broad concepts of Supportability Analysis and identifies options for location of maintenance including combinations of levels to achieve maximum cost-effectiveness. The outcome is a systemic maintenance program that prioritizes up-time and efficiency at the lowest cost.

LORA 101 – Fundamentals of Level of Repair Analysis

An introduction to the Level of Repair Analysis (LORA) process as it is applied for use in a Supportability Analysis. LORA is a process used to determine if corrective maintenance items should be repaired or discarded and at which maintenance level this should occur. The course provides instruction and practical application in performing LORA along with instruction on when a LORA should be performed within the life-cycle of a program. Intended for anyone performing LORA in support of Product Support Analysis (PSA).
