There were teething troubles - see EASA AD No.: 2017-0164
As an interim measure to address a potential unsafe condition in the landing gear actuators found in some in early machines, Leonardo designed a modification to inhibit the LG retraction for helicopters equipped with affected retraction actuators, and issued Bollettino Tecnico 169-005, providing instructions to install that modification on in-service helicopters. Leonardo also designed a modification to remove affected retraction actuators, allowing delivery of helicopters still on the production line. Subsequently, Leonardo developed improved LG retraction actuators that allow restoring the LG intended function, and issued Mandatory Bollettino Tecnico 169-018, providing instructions to install those actuators on in-service helicopters. Leonardo issued Alert Service Bulletin (ASB) 169-023, providing additional instructions to install improved control box and proximity switches, and to protect repetitively the plungers of the NLG and MLG up down lock actuators against corrosion.
Consequently, EASA issued AD 2017-0110 to require modification of helicopters by removing all affected LG retraction actuators from service, installing the improved LG retraction actuators, control box and proximity switches, and a one-time application of corrosion inhibitor on the plungers of the NLG and MLG up down lock actuators. Leonardo ASB 169-023 provides instructions for repetitive application of corrosion inhibitor. Since this is considered as standard practice maintenance, those actions were not required by that AD.
Question: Are there machines currently in service that are not able to retract their gear?
