SUPPLEMENTARY INFORMATION:
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20180270, dated December 12, 2018 EASA AD
20180270, to correct an unsafe condition for Leonardo S.p.A.
Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A.; and AgustaWestland Philadelphia Corporation, formerly Agusta Aerospace Corporation, Model AW119MKII helicopters, serial numbers 14831, 14834, 14838, 14840, 14841, 14842, 14843, 14844, 14901, 14904, 14905, 14906, and 14918. EASA advises that during maintenance of a helicopter,

removal of passenger windows could only be accomplished with difficulty.
EASA further advises that subsequent investigation identified a batch of helicopters on which passenger windows have been improperly installed during production. According to Leonardo Helicopters service information, an investigation concluded that the gasket was bonded to the window or on both sides instead of to the door frame.
This condition, if not corrected, could prevent the jettisoning of the windows, possibly preventing the evacuation of passengers during an emergency situation. Accordingly, EASA AD 2018
0270 requires removal and reinstallation of the passenger windows with the approved design data.
FAAs Determination The applicable model helicopter has been approved by EASA and is 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 the same type design.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Leonardo Helicopters Alert Service Bulletin No.
119094, dated November 15, 2018.
This service information specifies procedures for removing the standard windows installed on the affected helicopters and reinstalling them in accordance with approved design data.
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.
AD Requirements This AD requires, within 100 hours time-in-service after the effective date of this AD, removing and reinstalling the left-hand and right-hand windows by following certain procedures in the service information.
