Protect your engines with the Inlet Barrier Filter (IBF) which has a filtration rate of 99.8 %, thus eliminating the risk of Foreign Object Damage and premature engine wear. Once an aircraft is already in a P2/T2 configuration the conversion can be carried out by any approved maintenance center with a customized Service Bulletin for each individual aircraft. For all aircraft with an earlier build status, the respective SB compliance requirements apply. The duration of the retrofit depends on the starting configuration of the helicopter and the target configuration (with or with-out IBF). As an approximate time span, 20 working days can be expected for a retrofit with minimum content, up to 60 days for the most extensive retrofit (EC135 T1 CDS to H135). Benefit from the latest standards and convert your helicopter into an H135 for better performance and a higher resale value. EC135 to H135 Retrofit … CONVERT … and ...
