The current US Air Force fleet, whose planes are more than 23 years old on average, is the oldest in USAF history. It won’t keep that title for very long. Many transport aircraft and aerial refueling tankers are more than 40 years old – and under current plans, some may be as many as 70-80 years old before they retire. Indeed, even if the US military gets every plane it asks for in its future plans, average aircraft age will continue to rise. Nor is the USA the only country facing this problem.
As this dynamic plays out and average age continues to rise, addressing the issues related to aging aircraft becomes more and more important in order to maintain acceptable force numbers, readiness levels, and aircraft maintainability; avoid squeezing out recapitalization budgets; handle personnel turnover that becomes more and more damaging; and keep maintenance costs in line, despite new technical problems are arising that will present unforeseen difficulties. Like F-15 fighters under flight restrictions due to structural fatigue concerns. Or grounded entirely.
The biggest contracts aren’t always the ones deserving of the most attention. Enter the USA’s Joint Council on Aging Aircraft (JCAA) – and DID’s Spotlight article, which seeks to place the situation and its effects in perspective, via comments and articles that draw on senior sources within the US military and key outside observers….
The JCAA
The JCAA is a collaborative effort by the Navy, Marine Corps, Air Force, Army, Coast Guard, Defense Logistics Agency, Federal Aviation Administration (FAA), NASA and academia. The mission of the JCAA is to jointly identify, investigate and implement programs that will field products to improve the availability and affordability of all the services’ and agencies’ aging systems, and get fixes to the forces faster.
To that end, they will identify process recommendations and improvements, advocate and enable promising technology, help the transition of technology and other program opportunities, promote knowledge management (including conferences), and coordinate funding for promising solutions. The Academic Center on Aging Aircraft site has more information, and tends to be a better source than the JCAA site itself.
The JCAA has formed 5 technically oriented steering groups (wiring systems, avionics, corrosion, dynamic components, and structural health monitoring). These groups nominate technical initiatives in their areas, with identifiable products, to the JCAA and initiate planning towards delivering those products. Three areas have been identified by the JCAA as common problems including Diminishing Manufacturing Sources and Material Shortages (DMSMS), Training, and the Cost of Aging. Along with these strategic thrusts, a crisis in maintaining joint publications and keeping technical orders updated tops the JCAA agenda.
Contracts & Key Events

Unless otherwise specified, the Naval Air Warfare Center Aircraft Division in Patuxent River, MD issued the contract.
Nov 3/07: Following the crash of a Missouri Air National Guard F-15C aircraft Nov 2/07, the US Air Force suspended non-mission critical F-15 flight operations. The accident findings indicate a structural failure that caused the plane to break in two during flight. Japan follows suit, grounding its F-15Js and leaving Vietnam-era F-4 Phantom IIs as its primary air defense aircraft. Israel follows by grounding its F-15A-D/I fleet, too, as the effects widen. In the end, the entire American F-15 A-D fleet is down for 2 months, about 1/3 of the fleet remains grounded indefinitely, and serious rethinking is underway concerning a fleet that was expected to last into 2025. DID: “Aging Aircraft: USAF F-15 Fleet Grounded.”
Aug 6/07: Wyle Laboratories, Inc. in Huntsville, AL received a $9.2 million modification to a previously awarded firm-fixed-price, cost-plus-fixed-fee, cost-plus-award-fee contract (N00421-04-C-0121) to exercise an option for engineering and technical services in support of the Aging Aircraft Team and Joint Council on Aging Aircraft. Work will be performed in Lexington Park, MD and is expected to be complete in August 2008. Contract funds in the amount of $120,000 will expire at the end of the current fiscal year. The Naval Air Warfare Center Aircraft Division, Patuxent River, Md., is the contracting activity.
July 14/05: Wyle Laboratories Inc. in Huntsville, AL received an $8.5 million modification to a previously awarded firm-fixed-price, cost-plus-fixed-fee, cost-plus-award-fee contract (N00421-04-C-0121) to exercise an option for engineering and technical services in support of the Aging Aircraft Team and Joint Council on Aging Aircraft (JCAA). Work on this contract will be performed in Lexington Park, MD and is expected to be completed in August 2006. Contract funds in the amount of $800,000 will expire at the end of the current fiscal year.
Aug 3/04: Advanced Information Engineering Services (AI-ES) in Buffalo, NY received an $8.3 million ceiling-priced, firm-fixed-price, cost-plus-fixed-fee, cost-plus-award-fee contract to provide engineering and technical services in support of the Aging Aircraft Team and Joint Council on Aging Aircraft. Work will be performed in Lexington Park, MD and is expected to be complete in August 2005. Contract funds in the amount of $800,000 will expire at the end of the current fiscal year. This contract was competitively procured by a request for proposals and 4 offers were received by the Naval Air Systems Command in Patuxent River, MD (N00421-04-C-0121).

- DID Spotlight (Nov-Dec 2007)- Aging Aircraft: USAF F-15 Fleet Grounded. The result of a crash that revealed a structural flaw. Israel and Japan also grounded their F-15 A-D fleets, and the USAF’s grounding was lifted pending inspections, then re-imposed. A good illustration of the hazards inherent in dependence on aging aircraft fleets. Also includes details re: the USAF’s F-15 flight restrictions, which applied even before the crash.
- USAF (Nov 6/07) – Aging C-130s: the geriatric fleet. “One, affectionately known as “grandpa,” was built in 1961 and another was awarded an honorary Purple Heart for sustaining multiple mortar hits and ground fire during the Vietnam War…. “Due to the age of the aircraft we have a lot of electrical problems and cabin pressure problems… Old wires rub together and short out causing system malfunctions and component failures.”.... “There are some jobs which take a long time to work”.... “Due to different modifications the aircraft has had over the years the wiring diagrams get confusing.” ....changing the same parts multiple times takes a toll on equipment mounting points. “Parts stop fitting like they should….”
- Deutsche Welle (Nov 6/07) – Report: Half of Germany’s Military Planes are in Shambles. ”...corrosion and wear and tear have turned over half of Germany’s [C-160] Transall planes into decrepit machinery. The sources apparently said that it was becoming more difficult to locate spare parts for the planes, some of which are more than 40 years old…. Germany had originally planned to replace the remaining Transall planes with Airbus’ new A400M model by 2014, but that schedule may have to be revised due to recently announced delays in delivery.”

- Defense News (Oct 29/07) – Airplanes on Life Support. Moseley, Wynne Plead: Let USAF Pull the Plug. They’re talking about aircraft that can’t fly but must be kept per Congressional directives, which includes a number of C-130E Hercules and KC-135E Stratotankers. “One C-130E Hercules from the 86th Airlift Wing at Ramstein Air Base, Germany, is so old and in such bad shape it cannot safely fly. Yet U.S. Air Force maintainers must tow it around the tarmac every so often to make sure its tires don’t go flat, and crank up the engines every month to make sure they still run…. More than 20 percent of the service’s C-130Es are grounded or have significant flight restrictions…”
- USAF Association, Air Force Magazine (Sept 21/07) – Warning: USAF is “Going Out of Business” Quote: “Air Force Secretary Michael Wynne], speaking at a Washington think tank Sept. 19, said that the service’s stay-within-its-topline bootstrap approach isn’t arresting the aging aircraft problem, and the inventory age is still rising, from 23.9 years today to 26.5 years by 2012. The Air Force’s older fighters aren’t up to defeating a modern air defense system or modern foreign fighters, Wynne said…”
- Omaha World-Herald (May 15/07) – Air Force says wars strain resources. Gen. Ronald Keys, chief of the Air Combat Command, added more detail: “They do a great job keeping these planes flying, but the challenge with this kind of operational tempo is we don’t yet know what kind of toll all the fine dust (in Iraq) will take on all the connectors and parts in our airplanes…. When we fly these long missions in hot climates, you can get a kind of chronic heat effect on the pieces and parts of the aircraft.”
