Summary
EASA Airworthiness Directive 2019-0103 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all serial numbers of Leonardo S.p.A. AW189 helicopters. The directive addresses misleading information in the Rotorcraft Flight Manual emergency procedures related to the 'FUEL LOW' caution message. It mandates an update to the flight manual to ensure accurate estimation of remaining flight time under low fuel conditions.
What Changed
This directive requires amending the AW189 Rotorcraft Flight Manual by replacing specific pages in the emergency procedures section with updated content provided in Leonardo's Temporary Revision 3-1. The update clarifies that the remaining flight time after a 'FUEL LOW' caution depends on engine torque and fuel consumption, correcting the previous fixed 20-minute guidance. Incorporating later approved revisions containing the same updates is also acceptable for compliance.
Why It Matters
Accurate emergency procedures are critical for safe helicopter operation, especially under low fuel conditions. This update prevents pilots from misestimating remaining flight time, which could otherwise lead to uncommanded engine shutdowns and forced landings. Operators, maintenance, and compliance teams must ensure the flight manual reflects these changes to maintain regulatory compliance and enhance flight safety.
What To Do
Operators must amend section 3 of the AW189 Rotorcraft Flight Manual within 14 days of the effective date by exchanging pages 3-117A and 3-118 with those from Leonardo's Temporary Revision 3-1. All flight crews should be informed of the changes and operate the helicopter accordingly. Alternatively, incorporating a later approved RFM revision containing the same content satisfies the directive's requirements.
