Commercial aviation supply chain encompasses a broad umbrella of services including 145 Repair Stations, maintenance check facilities, and parts suppliers.
Together, these groups play an integral role in keeping aircraft across the world safe and efficient.
“Maintenance, repair and overhaul (MRO) services play an invaluable role in assuring that commercial airliners remain safe, durable and profitable,” says the IBM Institute for Business Value.
While the COVID-19 pandemic dealt a blow to the aviation industry, MROs are on the leading edge of a comeback.
“Maintenance suppliers, especially those providing a lot of spare parts and repair services for things like APUs or other sorts of mechanical systems that have a little bit higher tendency to break will have a shot of kind of clawing back that type of business sooner,” Jay Carmel, head of the aviation practice at global consulting firm Avasecent told Aviation International News.
Overall, aviation infrastructure, including MRO, is projected for huge growth from 2021 to 2026 according to a recent report.
Here is a close look at 145 Repair Stations, maintenance check facilities, and spare parts providers, all of which may ride the surge of growth in the next five years.
145 Repair Station Operators are maintenance facilities that have a certificate issued by the Federal Aviation Administration under Title 14 of the Code of Federal Regulations (14 CRF) Part 145 which allows them to perform certain maintenance, inspections and alterations of aircraft and aircraft products.
According to the FAA, a 145 Repair Station certificate is an “Air Agency Certificate” that refers to the aircraft repair services and tasks that a repair station is authorized to perform.
An FAA 145 Repair Station can only perform the functions necessary to inspect, repair, replace, or overhaul those aviation articles for which it has been approved. There are six general ratings that pertain to 145 Repair Station:
These six ratings are then broken down into specified classes that are further differentiated.
The FAA will routinely revoke the 145 Repair Station certificates for those operators that perform aircraft maintenance work that they are not authorized to perform.
FAA has an online Repair Station search that makes it easy to find a 145 Repair Station in your area by rating type.
In 1964 the FAA issued new rules in response to safety concerns and discoveries of weaknesses in the maintenance programs of some air carriers found during accident investigations and surveillance of operator maintenance activities.
The FAA Continuous Airworthiness Maintenance Program (CAMP) has been in place since.
The FAA does not approve maintenance programs, but it does issue air carrier operations specifications (OpSpecs) which authorizes carriers and operators to use a maintenance program and follow the air carrier maintenance manual required by the FAA.
The three primary objectives of air carrier maintenance programs are:
Inspections, called “checks” in aviation, are carried out all the time on a schedule geared to flight hours or cycles.
Aircraft maintenance checks are divided into four categories: A, B, C and D with A and B lighter checks and C and D more extensive checks:
Fixed-base maintenance operators, large companies that operate out of hangars at airports, perform C-Checks and D-Checks.
ATS, for example, has three heavy maintenance facilities capable of accommodating up to 36 aircraft at a single time with two located in Washington state and one in Kansas City.
All the 145 Repair Stations and maintenance check facility operators require spare parts to perform their repairs and maintenance and that is where they rely on spare parts providers.
MRO spare parts providers offer components that are fully traceable and overhauled by leading repair facilities and can be bought, leased or exchanged.
