[Docket No. FAA-2025-5436]


Agency Information Collection Activities: Requests for Comments; 
Clearance of a Renewed Approval of Information Collection: Reduction of 
Fuel Tank Flammability on Transport Category Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice and request for comments.

-----------------------------------------------------------------------

SUMMARY: In accordance with the Paperwork Reduction Act of 1995, FAA 
invites public comments about our intention to request the Office of 
Management and Budget (OMB) approval to renew a previously approved 
information collection. The current Fuel Tank Flammability Safety rule 
25.981 requires the Design Approval Holder (DAH) to report to the FAA 
on the component reliability of the fuel tank flammability reduction 
means. DAH as specified in AC 25.981-2A is the holder of any design 
approval, including type certificate, amended type certificate, 
supplemental type certificate, amended supplemental type certificate, 
Parts Manufacturer Approval (PMA), Technical Standard Order (TSO) 
authorization, letter of TSO design approval, and field approvals. As 
the transport aircraft fleet continues to fly longer than expected and 
component reliability may be affected or degraded, the data collection 
is needed on an on-going basis to ensure the aircraft fuel tank safety 
level continues to meet the predicted reliability at the time of 
certification. This collection of information supports the FAA's Safety 
Management System (SMS) safety goal and by proactively identifying 
hazards and mitigating risks before incidents occur.

DATES: Written comments should be submitted by May 14, 2026.

ADDRESSES: Please send written comments:

Forms, Fort Worth, Texas, by email at: [email protected]; phone: 817-222-5332/5220.

SUPPLEMENTARY INFORMATION: 
    Public Comments Invited: You are asked to comment on any aspect of 
this information collection, including (a) Whether the proposed 
collection of information is necessary for FAA's performance; (b) the 
accuracy of the estimated burden; (c) ways for FAA to enhance the 
quality, utility and clarity of the information collection; and (d) 
ways that the burden could be minimized without reducing the quality of 
the collected information. The agency will summarize and/or include 
your comments in the request for OMB's clearance of this information 
collection.
    OMB Control Number: 2120-0710.
    Title: Reduction of Fuel Tank Flammability on Transport Category 
Airplanes.
    Form Numbers: There are no FAA forms associated with this 
collection.
    Type of Review: Renewal of an information collection.
    Background: This is a Federal Register Notice with a 30-day comment 
period soliciting comments on the following collection of information 
for OMB Control Number 2120-0710. In accordance with 14 CFR 
25.981(b)(2) Fuel tank explosion prevention and Part 25 Appendix M25.5 
Fuel Tank System Flammability Reduction Means (FRM), the effects of 
aircraft component failures on the FRM reliability must be assessed on 
an on-going basis. All Design Approval Holders (DAH) as specified in AC 
25.981-2A such as Type Certificate (TC) holders and Parts Manufacturer 
Approval (PMA) holders must submit component reliability reports and 
flammability analysis documentation to demonstrate to their FAA 
Oversight Office and/or Certificate Management Office that they are 
compliant with the Fuel Tank Flammability Safety rule (73 FR 42443). 
Semi-annual reports submitted by DAH provide listings of component 
failures discovered during scheduled or unscheduled maintenance so that 
the reliability of the flammability reduction means can be verified by 
the FAA.
    The FAA received 2 anonymous comments published in the previous 
January 2026 Federal Register notice (91 FR 3626) supporting the 
subject data collection.
    Respondents: Approximately sixteen Design approval holders.
    Frequency: Every 6 months or 2 reports per year.
    Estimated Average Burden per Response: 40 hours each report.
    Estimated Total Annual Burden: 1280 hours.

    Issued in Des Moines, Washington, on April 10, 2026.

Deputy Technical Policy Branch Manager, AIR-620, Policy & Standards 
Division, AIR-600, Aircraft Certification Service.
