Leonardo S.p.a. Model AB139 and AW139 helicopters with 3-stretcher kit part number 139084501 installed by a certain supplemental type certificate STC. EASA advises that a design deficiency was identified, affecting the primary stretcher unit, part number 002095502, of the 3-stretcher kit part number 139084501. This condition, if not addressed, could lead, in case of an emergency landing, to failure of the primary stretcher of the 3-stretcher kit, possibly resulting in injury to helicopter occupants.
Accordingly, EASA AD 20210095
requires installing a placard on the primary stretcher stating a limitation of 61 kg 134.5 lbs for the maximum allowable weight of the occupant on the primary stretcher. EASA considers its AD an interim action and states that further AD action may follow. Although EASA AD 20210095 applies to Leonardo S.p.a. Model AB139 and AW139 helicopters with 3-stretcher kit part number 139084501 installed by a certain STC, this AD applies to helicopters with an affected part installed instead.
FAAs Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.

CFR Part 51
The FAA reviewed Aerolite Alert Service Bulletin ASB21006, dated March 16, 2021. This service information specifies procedures for installing a weight limit placard on the primary stretcher unit of the 3-stretcher kit.
This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
