AD 2019-22-13

The FAA is adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by reports of lavatory waste bin fire extinguishers found depleted. This AD requires a one-time inspection of the installation of the waste bins for interference (the inspection also includes a weight check of the waste bin fire extinguisher and an inspection of the discharge tubes for damage), modification of affected waste bins, and replacement of affected fire extinguishers, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also requires replacement of the fire extinguisher if any damaged discharge tube is found or the weight of the waste bin fire extinguisher is too low. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

2019-22-13 Fokker Services B.V.: Amendment 39-19792; Docket No. FAA- 2019-0666; Product Identifier 2019-NM-086-AD.

(a) Effective Date

This AD is effective December 30, 2019.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.

(d) Subject

Air Transport Association (ATA) of America Code 25, Equipment/ Furnishings.

(e) Reason

This AD was prompted by reports of lavatory waste bin fire extinguishers found depleted. An investigation revealed that damage to the discharge tubes may have occurred during installation or removal of the waste bin. Insufficient clearance between the waste bin and the fire extinguisher discharge tubes may have caused the discharge tubes to collide with the waste bin and discharge. The FAA is issuing this AD to address this condition, which could result in failure to discharge the extinguishing agent during a lavatory bin fire, and consequent damage to the airplane and injury to occupants.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Requirements as Specified in EASA AD 2019-0095

Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2019-0095, dated April 30, 2019 (``EASA AD 2019-0095'').

(h) Exceptions to EASA AD 2019-0095

(1)Where EASA AD 2019-0095 refers to its effective date, this AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2019-0095 does not apply to this AD.

(i) Additional Requirement: Corrective Action

If, during any inspection required by paragraph (1) of EASA AD 2019-0095 (which includes a weight check of the waste bin fire extinguisher and an inspection of the discharge tubes for damage), any damaged discharge tube is found or the weight of the waste bin fire extinguisher is too low: Before further flight, replace the fire extinguisher with a serviceable fire extinguisher.

(j) Other FAA AD Provisions

The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Section, Transport Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the International Section, send it to the attention of the person identified in paragraph (k) of this AD. Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or Fokker Services B.V.'s EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0095, dated April 30, 2019 (``EASA AD 2019-0095'') (also referred to as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. The NPRM published in the Federal Register on August 30, 2019 (84 FR 45697). The NPRM was prompted by reports of lavatory waste bin fire extinguishers found depleted. The NPRM proposed to require a one-time inspection of the installation of the waste bins for interference (the inspection also includes a weight check of the waste bin fire extinguisher and an inspection of the discharge tubes for damage), modificationof affected waste bins, and replacement of affected fire extinguishers. Then NPRM also proposed to require replacement of the fire extinguisher if any damaged discharge tube is found or the weight of the waste bin fire extinguisher is too low.
The FAA is issuing this AD to address insufficient clearance between the waste bin and the fire extinguisher discharge tubes, which could result in failure to discharge the extinguishing agent during a lavatory bin fire, and consequent damage to the airplane and injury to occupants. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

EASA AD 2019-0095 describes procedures for a one-time inspection of the installation of each affected waste bin for interference between the waste bins and the fire extinguisher discharge tubes (the inspection for interference also includes a weight check of the waste bin fire extinguisher and a detailed inspection of the discharge tubes for damage), modification of affected waste bins, and replacement of affected fire extinguishers. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

The FAA estimates that this AD affects 4 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 1 work-hour x $85 per hour = $85............................. $0 $85 $340 ----------------------------------------------------------------------------------------------------------------

The FAA estimates the following costs to do any necessary on- condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions:

Estimated Costs of On-Condition Actions ----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- 3 work-hours x $85 per hour = $255............................................ $1,100 $1,355 ----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

[[Page 64730]]

This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
