Models named: F28 Mark 0100. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Fokker Services B.V. Model F28 Mark 0100 airplanes, certificated in any category, serial numbers 11244 through 11527 inclusive, except those airplanes modified in service as specified in Fokker Service Bulletin SBF100-25-070, or Fokker Service Bulletin SBF100-25-109, or Fokker Modification Report FS-N545 or FS-N571.

Required actions
This paragraph restates the requirements of paragraph (f) of AD 2005-12-16, with clarified note. Within 36 months after July 20, 2005 (the effective date of AD 2005-12-16), inspect to determine if Grimes Aerospace PSU panels having part number (P/N) 10-1178-() or P/N 10-1571-() are installed and the PSU modification status if applicable, and do any corrective actions if applicable, by doing all of the actions specified in the Accomplishment Instructions of Fokker Service Bulletin SBF100-25-097, dated December 30, 2003. Note 1 to paragraph (g) of this AD: Guidance on modifying the PSU panel can be found in Fokker Service Bulletin SBF100-25-097, dated December 30, 2003, which refers to Grimes Aerospace Service Bulletin 10-1178-33-0040, Revision 1, dated March 25, 1996 (for PSU panels having P/N 10-1178-()); and Grimes Aerospace Service Bulletin 10-1571-33-0041, dated October 15, 1993 (for PSU panels having P/N 10-1571-()).
Unsafe condition
This AD was prompted by reports of smoke in the passenger compartment during ground operations and in flight, and a determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly. We are issuing this AD to detect and correct overheating of the passenger service unit (PSU) panel due to moisture ingress, which could result in smoke or fire in the passenger cabin.
Affected ADs
This AD replaces 2005-12-16, Amendment 39-14132 (70 FR 34642, June 15, 2005) (“AD 2005-12-16”).
