Action
Final rule; request for comments.
Summary
This final rule extends the compliance deadline for supplemental type certificate holders to complete safety assessments of their fuel tank systems, and any system that may affect the fuel tank system, and to develop design changes and maintenance programs needed to correct unsafe conditions. It also extends the compliance time for the affected operators to incorporate instructions for maintenance and inspection of the fuel tank system into their maintenance or inspection programs. This action is needed to allow supplemental type certificate holders additional time to complete their compliance submittals using a newly identified method of completing their safety assessments and identifying corrective actions without acquiring information from the type certificate holders. Because the operators are dependent upon the supplemental certificate holders for showing compliance with the operating rules, this rule allows them the same time extension.
