Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2012-22- 15 for all Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. AD 2012-22-15 currently requires revising the maintenance program to incorporate the limitations, tasks, thresholds, and intervals specified in certain revised Fokker maintenance review board (MRB) documents. Since we issued AD 2012-22-15, we received new revisions of airworthiness limitations items (ALI) documents, which introduce new and more restrictive maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. We are proposing this AD to prevent the unsafe condition on these products.
