SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain United Instruments, Inc. 5934 series altimeters that were manufactured between January 2015 and February 2016 and installed in airplanes and helicopters. The NPRM published in the Federal Register on November 7, 2016 (81 FR 78083). The NPRM was prompted by a report that certain 5934 series altimeters that were manufactured between January 2015 and February 2016 may display higher than actual altitude. These altimeters are susceptible to developing a slow diaphragm leak, which would affect the accuracy of the altimeters. It has been determined that insufficient removal of chemical substance on the diaphragm assembly during the production process of the altimeter caused the misleading display of altitude data. The NPRM proposed to require replacing the affected altimeters. We are issuing this AD to prevent display of misleading altitude data, which could result in inadvertent flight into terrain. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM.

This service information 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 We estimate that this AD affects 1,351 altimeters as installed in airplanes and helicopters of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Replace altimeter .................... 1 work-hour × $85 per hour = $85 ......................................... According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. We are 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to The Boeing Company Model 777–200 and –300 series airplanes equipped with Rolls-Royce Model Trent 800 engines. The NPRM published in PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 12397 the Federal Register on March 17, 2016 (81 FR 14402). The NPRM was prompted by reports of damage to the upper bifurcation forward fire seal and seal deflector, and localized damage to the insulation blanket installed just aft of the fire seal. The NPRM proposed to require installing serviceable left and right T/R halves on the left and right engines. We are issuing this AD to prevent a breach in the engine firewall due to a failed upper bifurcation forward fire seal. A breach could delay or prevent the fire detection and suppression system from functioning properly, and could result in an increased risk of a fire, prolonged burning, and breach of the fire zone; and could allow fire to reach unprotected areas of the engine, the strut, and wing after engine shutdown. Also, fan air bypassing the fire seal could cause localized damage to the T/R insulation blanket installed just aft of the fire seal, which could allow limited thermal degradation of the T/R inner wall. This could aggravate existing damage and cause the T/R’s inner wall to fail. Actions Since the NPRM Was Issued In the Other Relevant Rulemaking section of the NPRM we mentioned additional proposed rulemaking related to the T/Rs for Model 777–200 and –300 series airplanes equipped with RollsRoyce Model RB211–Trent 800 engines. That action was subsequently issued as a supplemental NPRM (SNPRM), Docket Number FAA–2011–0027, Directorate Identifier 2010–NM–127–AD, which was published in the Federal Register on September 25, 2015 (80 FR 57744). The final rule for that SNPRM has been issued and was published in the Federal Register on June 17, 2016 (81 FR 39547), as AD 2016–11–16, Amendment 39– 18543. Since the NPRM was issued, the European Aviation Safety Agency (EASA) issued EASA AD 2016–0084, dated April 28, 2016, for Rolls-Royce RB211-Trent 800 engines; and the Engine Certification Office (ECO), Engine and Propeller Directorate, FAA, issued a corresponding NPRM, Docket No. FAA–2016–6692, Directorate Identifier 2016–NE–13–AD, which was published in the Federal Register on July 15, 2016 (81 FR 46000). In the EASA AD and FAA ECO NPRM, damage (cracking, missing materials, and hole/ openings) to the engine upper bifurcation fairing panel creates a breach of the engine fire wall, which may decrease the effectiveness of the engine fire detection and suppression systems due to excess fan air entering the engine compartment fire zone.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain United Instruments, 
Inc. 5934 series altimeters that were manufactured between January 2015 
and February 2016 and installed in airplanes and helicopters. The NPRM 
published in the Federal Register on November 7, 2016 (81 FR 78083). 
The NPRM was prompted by a report that certain 5934 series altimeters 
that were manufactured between January 2015 and February 2016 may 
display higher than actual altitude. These altimeters are susceptible 
to developing a slow diaphragm leak, which would affect the accuracy of 
the altimeters. It has been determined that insufficient removal of 
chemical substance on the diaphragm assembly during the production 
process of the altimeter caused the misleading display of altitude 
data. The NPRM proposed to require replacing the affected altimeters. 
We are issuing this AD to prevent display of misleading altitude data, 
which could result in inadvertent flight into terrain.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed United Instruments, Inc. Service Bulletin No. 13, dated 
March 25, 2016. The service bulletin describes procedures for replacing 
the nonconforming altimeters. This service information 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

    We estimate that this AD affects 1,351 altimeters as installed in 
airplanes and helicopters of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Replace altimeter..................  1 work-hour x $85 per hour           $1,600          $1,685      $2,276,435
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
    We are 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.

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

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

2017-04-06 United Instruments, Inc.: Amendment 39-18801; Docket No. 
FAA-2016-9345; Directorate Identifier 2016-CE-028-AD.

(a) Effective Date

    This AD is effective April 7, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to United Instruments, Inc. 5934 series 
altimeters that were manufactured between January 2015 and February 
2016 and installed in airplanes and helicopters.
    (1) The specific affected serial number altimeters can be found 
in United Instruments, Inc. Service Bulletin No. 13, dated March 25, 
2016. Paragraph (j)(3) of this AD contains addresses for obtaining 
the service bulletin.
    (2) Altimeters that have been corrected by United Instruments, 
Inc. following Service Bulletin No. 13, dated March 25, 2016, are 
not affected by this AD and no further action is necessary.
    (3) Altimeters that have been corrected by United Instruments, 
Inc. can be identified by a yellow dot, approximately \1/4\ inch (6 
mm) in diameter, located approximately 1 inch (25 mm) to the left 
side of the nameplate. The corrected altimeters will also have a 
letter ``M,'' approximately \1/8\ inch (3mm) high, metal stamped on 
the nameplate after the name ``ALTIMETER.''

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 44, Cabin Systems.

(e) Unsafe Condition

    This AD was prompted by reports of certain altimeters displaying 
higher than actual altitude due to a slow diaphragm leak. We are 
issuing this AD to prevent display of misleading altitude data, 
which could result in inadvertent flight into terrain.

(f) Compliance

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

(g) Replacement

    Within the next 12 months after April 7, 2017 (the effective 
date of this AD), replace any affected altimeter with a serviceable 
part following United Instruments, Inc. Service Bulletin No. 13, 
dated March 25, 2016.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita Aircraft Certification Office (ACO), 
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 manager of the ACO, send it to the 
attention of the person identified in paragraph (i) of this AD.
