Aero Union Corporation was an aircraft operation and maintenance company based in Chico, California, United States. They were known for operating fire fighting aircraft, training crews in aerial firefighting and making custom designed fire fighting systems tailored to specific aircraft requirements. After years of controversies regarding the operation of the company and the safety of their planes the U.S. Forest Service canceled its contract and the company was forced to shut down operations soon after.
In 1960 Dale Newton and Dick Foy participated in their first fire season with a surplus B-25 Mitchell. Newton & Foy operated for that season under the name Western Air Industries. The following year they purchased their first two B-17 Flying Fortresses and changed their name to Aero Union. In 1962 the company moved their operations from Redding, California to Chico. Between 1975 and 2000, the company used Douglas C-54 aircraft as tankers and as general support aircraft, nine being in use in April 1990.
Move from Chico
In June 2010 Aero Union announced plans to move the majority of its operations to McClellan Airfield (formerly McClellan Air Force Base) just outside of Sacramento. Reasons stated for the move include needing larger, more consolidated facilities, access to a larger labor pool and being closer to its primary customers. A smaller scale Chico operation continued to be maintained for several months to provide additional storage and flexibility. The relocation began in September 2010 but ended abruptly with the closure of the company.
Aero Union was one of the contractors involved in the U.S. Forest Service airtanker scandal. With the grounding of the U.S. Forest Service's aging C-119 Flying Boxcar fleet in 1987 (some of which were operated by Aero Union) due to safety concerns the Forest Service found its aerial fire fighting capability greatly reduced. In order to quickly replace the retired aircraft and modernize the fleet the USFS, organized a deal with the Department of Defense and the General Services Administration to exchange the grounded planes with more modern C-130a Hercules and P-3 Orion aircraft. The unpublicized exchange program eventually allowed six different contractors to acquire twenty-eight aircraft at no cost, without a bidding process or public access. The exchange of these aircraft was found to have been illegally carried out by the USFS and instead of merely allowing the contractors to operate the aircraft many of their titles were transferred, effectively giving many of the aircraft away for free. At least four of the planes transferred were dismantled for parts by Aero Union and TBM. Aero Union exchanged planes with the USFS, with the government retaining the titles and ownership, and was charged with maintaining and operating them for firefighting duties. Instead Aero Union dismantled some of their planes and sold the parts for a profit. Aero Union made an out of court settlement with the government over its actions but this was later challenged in court.
On July 29, 2011 the U.S. Forest Service announced that it had canceled its 6 plane contract with Aero Union after the company's planes failed their required safety inspections. In April 2011 Aero Union had voluntarily disclosed that its planes were not current on inspections and were in violation of the contract. The contract, worth about $30 million a year, made up about 95% of the company's income. Less than a month later Aero Union informed its employees that they were out of work and that the company was shutting down operations. That August Aero Union failed to make its lease payments to the City of Chico and the lease was declared invalid by the city that September due to concerns that the city would be unable to re-lease the facilities if they became tied up in bankruptcy proceedings. Reduced to a staff of 5 people after the last round of layoffs, down from approximately 230 in 2008, CEO Brett Gourley claimed “The company is in sort of hibernation mode” and was looking for other sources of income. Aero Union has since completely shutdown all of its facilities, websites and other points of contact and is assumed to be out of business. In February 2012 PMI held an auction of Aero Union's aircraft assets, including 8 P-3 Orion aircraft, various spare parts and their intellectual property (MAFFS II and FIREHAWK firefighting systems). Only 2 aircraft were bid upon and those bids were rejected as being too low. In May 2012 another auction of tools and equipment, but no aircraft, parts or intellectual property, went through with the majority of it selling.
One of the company's last projects was an improved version of the Modular Airborne FireFighting System under contract to the U.S. Forest Service. Originally designed for C130 J-model aircraft and later modified to fit on C130 H models, the new MAFFS II system has a capacity of up to 3,400 gallons, replacing the five retardant tanks with one large tank, and has an on-board air compressor. The original MAFFS has to be pressurized by a compressor on the ground as a part of the loading process. The ability to pressurize the system in the air will cut turn-around time but yet, add substantial weight. The new system discharges the retardant through a special plug in the paratroop drop door on the side of the aircraft, rather than requiring the cargo ramp door to be opened; this allows the aircraft to remain pressurized during the drop sequence.
Aero Union delivered the first production unit to the USFS in July, 2007, with flight testing that following August. MAFFS II was used for the first time on a fire in July 2010. Since the closure of Aero Union there are no longer any companies building or supporting the MAFFS II system.
