What to do
Operators must perform initial and repetitive inspections of the tail boom/Fenestron junction frame within specified flight hour intervals, following Airbus Helicopters' service bulletin instructions. If cracks are found, corrective actions must be taken based on crack severity, including contacting Airbus Helicopters for approved repair instructions. Modification 074775 must be embodied as terminating action for inspections, with compliance deadlines specified relative to the original AD effective date.
Summary
EASA Airworthiness Directive 2014-0114R2 is an updated regulatory requirement addressing inspection and repair of the tail boom and Fenestron junction frame on Airbus Helicopters EC 130 B4 models. It applies to all serial numbers except those with specific reinforcement modifications or approved repairs. The directive mandates repetitive inspections to detect cracks that could lead to structural failure and potential loss of helicopter control.
What changed
This revision removes the requirement to implement modification 074609 and confirms that modification 074775, which involves installing carbon patches, is the preferred terminating action for repetitive inspections. It also introduces a new inspection interval for helicopters modified with 074775 and updates inspection procedures accordingly.
Why it matters
This directive is critical for maintaining the structural integrity of the tail boom and Fenestron junction frame, preventing potential detachment and loss of control. Operators and maintenance organizations must comply to ensure continued airworthiness and safety of the EC 130 B4 fleet. It affects maintenance planning, inspection schedules, and repair procedures.
