After research and testing, it was determined that the installation of snow baffles on the Bell 206L caused a change in air pressure in the vicinity of the filter static reference port significant enough to skew readings. A solution to the irregularity has been developed, tested and approved by the FAA. This solution results in a more accurate static source reading when flying with snow baffles installed. It is necessary to relocate the filter static reference port to prevent early filter clogged annunciator illumination. 2.0 COMPLIANCE Mandatory Service Bulletin 3.0 COMPLIANCE TIME Prior to flying with Snow Baffles installed. 3920 Sandstone Drive, El Dorado Hills, CA 95762, USA Phone 415-884-0555 Fax 415-884-0505 Page 2 of 3 4.0 SPARE KIT AVAILABILITY To procure kits, contact FDC Customer Support Order: 1x p/n 1206K1-1 Static Port Relocation Kit per aircraft Indicate aircraft S/N(s) and kit quantity(s) 5.0 INSTALLATION TIME Est. 3-4 man-hours. 6.0 WEIGHT & BALANCE Not Affected 7.0 FLIGHT MANUAL REVISION Not Affected 8.0 DOCUMENTS Refer to original STC documents. 9.0 INSTALLATION INSTRUCTIONS Refer to instructions included with kit. 3920 Sandstone Drive, El Dorado Hills, CA 95762, USA Phone 415-884-0555 Fax 415-884-0505 Page 3 of 3 SERVICE BULLETIN COMPLIANCE NOTIFICATION SB.FDC.B206L.0009 Rev D TO : FDC/aerofilter Technical Support FROM : COMPANY : AIRCRAFT : S/N(s) PHONE : FAX : EMAIL : DATE : I have complied with FDC SB.FDC.B206L.0009 Rev D NAME : POSITION : A&P NO : DATE : SIGNED : ...................................................
