Quality Aviation

What Quality Aviation does

Quality Aviation Inc. is a privately held aerospace parts distributor and service organization headquartered in Fontana, California. Founded more than 50 years ago and operating from a 250,000 square foot warehouse facility, the company holds an inventory of over 540,000 different line items and is ISO 9001:2015 certified, with the ability to issue DD250 and DD1574 military certifications on its products. The company serves four primary customer segments — US Military, Allied Nations/International Military, Commercial Aviation, and Industrial Power Generation — and supports a broad range of legacy and current aircraft platforms, including fighters (F-4, F-5, F-16, A-10), cargo/transport aircraft (C-130, C-5, KC-135), helicopters (AH-1, S-61, UH-1), and commercial types from B707 through B767 and A300 through A340, as well as industrial turbines (LM1500, LM2500, GG3, GG4, LM100).

The company's core products fall into four lines: Military Aircraft Spares, Military Engine Parts & Exchanges (GE J79/J85/T58/T64/F110, Pratt & Whitney J52/J57/TF30, Allison TF41/T56), Industrial Engines (with full OHC/repair capability on the LM1500), and Commercial Aircraft Parts & Services. These product lines are underpinned by a self-service Parts Search inventory tool and an extensive proprietary technical library containing prints, drawings, technical orders, overhaul manuals, TCTOs, and illustrated parts manuals, along with engineering support data for McDonnell Douglas and General Electric products. Value-added services include exchange programs (overhauled components and engines swapped for customer cores), OHC overhaul and repair services with 24/7 availability, and the ability to identify alternate part numbers with Fit-Form-and-Function equivalence or Next Higher Assembly configurations.

Quality Aviation generates revenue primarily through one-time parts sales (factory new, new surplus, and overhauled units) and professional services revenue from engine overhaul, component repair, and exchange programs. Pricing is predominantly quote-based (RFQ) with some specialty items published (e.g., $250,000 QEC C-130 Power Plant Assembly, $47,500 C-130 Oil Cooler Assembly in new surplus condition, $36,000 overhauled). Go-to-market is a traditional sales-led B2B motion with department-segmented sales contacts (US Customers, US Government, International Customers), supported by a website Parts Search tool and an RFQ email channel ([email protected]). The company has no disclosed external investors, parent, or subsidiaries, and is led by CEO Earlene Castro with a small named management team spanning Operations, IT/Export Administration/Marketing, Quality Assurance, Sales, Contracts, and Purchasing.

Core offering

Quality Aviation distributes new, surplus, and overhauled aerospace parts for military, commercial, and industrial aircraft and gas turbine engines, sourcing from qualified manufacturing facilities and stocking over 540,000 line items in a 250,000 square foot warehouse. The company also provides turbine engine overhaul, repair, and exchange services, backed by an extensive private technical library covering aircraft, engines, and engineering support.

Product overview

Quality Aviation operates as an aerospace parts distributor and service organization with a single-site integrated model. The core offering centers on the Parts Search inventory system (accessing 540,000+ line items), supported by four product lines: Military Aircraft Spares (supporting fighter, cargo, and rotary aircraft plus subsystems), Military Engine Parts & Exchanges (GE, Pratt & Whitney, Allison turbine engines), Industrial Engines (power generation turbines with OHC capability), and Commercial Aircraft Parts & Services (covering regional to widebody aircraft). These product categories are complemented by Technical Support Services (technical library and engineering assistance) and OHC Repair Services (in-house and subcontracted turbine overhaul). The Commercial and Military divisions share overlapping capabilities (e.g., C-130 support, Allison engines) while maintaining separate inventory and service tracks.
