Blackhawk Group Receives STC for TBM Engine Upgrade

Blackhawk Group Secures FAA Approval for TBM Engine Upgrade
The Blackhawk Group has obtained Federal Aviation Administration (FAA) approval for its XP66D Engine+ Upgrade, specifically developed for the Daher TBM 700 series aircraft. This Supplemental Type Certificate (STC) represents a significant achievement for the company. The initial installation of the upgraded engine is currently in progress at Blackhawk’s headquarters in Waco, Texas, with a second installation planned at the AVEX Performance Center in Broomfield, Colorado.
Enhanced Performance and Efficiency
The XP66D upgrade replaces the original 700-horsepower PT6A-64 engine with the more powerful 850-horsepower PT6A-66D, resulting in a 21% increase in shaft horsepower. Flight tests have demonstrated substantial performance gains, including a reduction in climb time to flight level 310 from 28 minutes to 22 minutes. Additionally, the maximum cruise speed has increased by an average of 25 knots true airspeed, reaching up to 303 KTAS. Beyond improved climb and cruise capabilities, Blackhawk officials highlight that the upgrade also lowers operating costs and enhances safety margins by providing greater available power at altitude.
Market Implications and Industry Response
While the FAA certification positions Blackhawk Group as a leader in TBM 700 performance enhancements, the company may encounter challenges related to market acceptance and integration with existing aircraft fleets. Industry analysts suggest that competitors might respond by developing similar engine upgrades to maintain their market positions. Market reactions are expected to be mixed; some operators may rapidly adopt the XP66D to capitalize on its performance and efficiency benefits, whereas others may adopt a more cautious stance, awaiting further data on reliability and long-term cost-effectiveness.
The wider aviation sector is closely monitoring the rollout of the XP66D upgrade to evaluate its impact on operational costs and maintenance schedules for TBM 700 operators. As initial installations proceed, the real-world performance and economic implications of the upgrade will likely shape future adoption trends and competitive dynamics within the turboprop market.
