- Jun 8, 2026Rotor Blade Repair, Inc.OpposeBusiness📎 Attachment
Rotor Blade Repair, Inc. and 5 States Helicopters, Inc. oppose the proposed airworthiness directive, arguing that it incorrectly conflates different type certificates and improperly restricts maintenance to specific Sikorsky-authorized facilities. They request the withdrawal of the proposal, citing concerns over configuration control, regulatory non-compliance, and the potential for maintenance errors.

Firehawk Helicopters, Inc. opposes the proposed Airworthiness Directive, arguing that the FAA has not provided sufficient evidence that the unsafe condition exists in civilian aircraft with different operating profiles than military ones. The company asserts that their own fleet has not experienced the issues and that the FAA should provide a more reasoned, record-based explanation before requiring new T/R blades.

Billings Flying Service, LLC, a subsidiary of Quanta Services, Inc., requests that the FAA withdraw the proposed airworthiness directive in its entirety. They argue that the FAA exceeds its authority under 14 CFR § 39.5 by attempting to apply a corrective action to multiple helicopter types that do not share the "same type design."

Shawn Harris, President/CEO of 5 State Helicopters, Inc., opposes the proposed action. He argues that the FAA is violating its own regulations regarding type designs and questions the lack of supporting data for the effort.

5 State Helicopters, Inc., a helicopter operator, opposes the proposed Airworthiness Directive because it appears to apply broadly across different UH-60 type designs without sufficient technical justification. They argue that the FAA has not demonstrated how an unsafe condition in one specific design applies to others and request clear engineering evidence before proceeding.
