ISO 9001:2015

HFE International continues to improve quality and reliability of their engines.  The latest effort involved implementing a standard quality control system that organizes and maintains the idea of continued improvement through process.  Over the past year, everyone at the company including engineers, accounting, management, and technicians contributed in the development of the quality system and processes.  CEO Tom West made the decision to become the company’s quality supervisor and management representative.  With this move, all involved in the organization respect, and participate in the process as a “Top Down” approach to the serious nature of producing a defect free, quality product. HFE International has now been certified as an ISO 9001:2015 company by Perry Johnson Registrars.  

20,000 ft Flight Testing

To date, HFE International has operated the DA 70 and DA 150 at altitudes of 20,000 ft.  In both cases, the engines performed as designed.  Degradation in power was relative to air density as estimated.   Both the Mil Spec and commercial EFI systems were flown at 20,000 feet showing that the EFI systems are compensating for fuel with barometric pressure change.  In the case of the DA 150, the engine was shut off at 20,000 feet (on purpose) as a test of the starter system.  The engine was then re-started to determine if the alternator had enough torque and capacity at 20,000 feet.  The engine re-started without issue.   This test was completed multiple times with no issue. Altitude testing can be a challenge for aircraft […]
