Daher has selected Elliott Aviation to install the HomeSafe™ emergency autoland system on TBM 940 very fast turboprop aircraft delivered in the U.S. market during 2019 and the first half of 2020.
TBM 940s to be equipped by Elliott Aviation were supplied by Daher prior to last month’s certification of HomeSafe™. A portion of these aircraft were sold to include the autoland system upgrade once HomeSafe™ was approved by the airworthiness authorities, while others are eligible for retrofit as a customer option.
HomeSafe™ is based on Garmin’s emergency autoland technology, which brings the aircraft to a runway touchdown if the pilot becomes incapacitated.
Nicolas Chabbert, the Senior Vice President of Daher’s Aircraft Division, said Elliott Aviation’s capabilities and resources were primary reasons for the selection of this TBM Network member to undertake the comprehensive scope of work involved in HomeSafe™ upgrades/retrofits.
“Elliott Aviation provides a solution for timely execution of the HomeSafe™ installations on aircraft from almost half of this year’s production output, which require multi-competency expertise for work that will be performed to factory standards,” Chabbert explained. “The company also has committed the necessary dedicated resources for an extended period of time to accommodate the availability of TBM 940s for retrofits and upgrades.”
He added that exceptional support is planned for the TBM 940s involved in the HomeSafe™ system outfitting, including direct assistance by Daher’s TBM network.
The autoland system’s outfitting process involves such tasks as modification of the aircraft’s braking system (including the installation of a larger hydraulic fluid tank, the addition of a dedicated master cylinder with servo and control linkage); along with wiring changes and integration of electrical relays to enable automatic activation of the flaps, landing gear and landing lights. A fuel shut-off valve is added to stop the engine by cutting off the fuel supply, while the cockpit’s glareshield is modified to include the HomeSafe™ activation button.
At completion of the work, a comprehensive software upgrade is performed, including configuration management, followed by dedicated ground tests.
