Eagle Copters gets 407HP FAA approval for IBF

July 21, 2016  By Eagle Copters

Eagle Copters has announced its Eagle 407HP, powered by the Honeywell HTS900 engine, received United States Federal Aviation Administration (FAA) supplemental type certificate (STC) approval for the company’s inlet barrier filter (IBF).

This will allow operators to tackle various para-public missions including law enforcement, fire suppression, cone harvesting, aerial seeding, power and pipeline patrols as well as operate in sandy conditions.

“This is certainly an important milestone for the maturing Eagle 407HP program,” said Stephane Arsenault, vice-president, sales and marketing, Eagle “Operators have been looking forward to this feature since the inception of the program and by providing this level of engine protection, the Eagle 407HP will continue to expand into both new para-public and traditional general utility helicopter markets.”

Arsenault also added: “The design for the 407HP needed to be all encompassing for the various inlet configurations that could be received with customers’ helicopters. The IBF was optimized for the Honeywell engine installation while accommodating previous inlet modifications. The new inlet barrier filter design exceeds the performance capabilities of prior certified systems with more filter area, multiple flow paths and a far less complicated bypass system.”

The newly certified IBF was developed with consideration for evolving Transport Canada Civil Aviation and FAA certification guidance. A significant strength in this project was assistance from Honeywell in developing the installation and the inlet performance analysis. FAA has issued a supplemental type certificate (STC) for the Eagle 407HP.


All aspects of the IBF installation were investigated and performance verified. The performance charts for the aircraft reflect the verified engine installation losses and reflect the outstanding performance capability of the Eagle 407HP.

The Eagle 407HP is a Bell 407 powered by the Honeywell HTS900 engine – enabling 22 percent more shaft horsepower, 19 percent payload increase, lower engine direct maintenance costs, lower fuel burn and the safety of a dual channel FADEC. Currently approved in Canada, United States, Mexico, Chile and Australia with other foreign validations pending
