1 [Federal Register Volume 78, Number 6 (Wednesday, January 9, 2013)] [Rules and Regulations] [Pages ] From the Federal Register Online via the Government Printing Office [ [FR Doc No: ] DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA ; Directorate Identifier 2012-NM-191-AD; Amendment ; AD ] RIN 2120-AA64 Airworthiness Directives; Honeywell International Inc. Air Data Pressure Transducers AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. SUMMARY: We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. This AD requires various tests or checks of equipment having certain air data pressure transducers, and removal of equipment if necessary. As an option to the tests or checks, this AD allows removal of affected equipment having certain air data pressure transducers. This AD was prompted by a report of a pressure measurement error in the pressure transducer used in various air data systems, which translates into air data parameter errors. We are issuing this AD to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. These errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. DATES: This AD is effective January 24, The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of January 24, We must receive comments on this AD by February 25, ADDRESSES: You may send comments, using the procedures found in 14 CFR and 11.45, by any of the following methods: Federal erulemaking Portal: Go to Follow the instructions for submitting comments.

FOR FURTHER INFORMATION CONTACT: Blake Higuchi, Aerospace Engineer, Systems and Equipment Branch, ANM-130L, FAA, Los Angeles Aircraft Certification Office, 3960 Paramount Boulevard, Lakewood, CA ; phone: ; fax: ; SUPPLEMENTARY INFORMATION: Discussion We received a report of a pressure measurement error in the air data pressure sensor used in various air data systems, which translates into air data parameter errors, possibly related to sleeks (micro-scratches on the polished glass tube pressure port) and the anodic bond of the glass tube to the sensor die. Errors in the pressure sensor measurements could impact other aircraft systems using the pressure measurements. The primary concern is the impact on the air data system and the associated airspeed (Mach, computed airspeed, and true airspeed) and computations. This error in the static pressure measurement will result in a higher indicated altitude than the actual altitude and a higher indicated airspeed than actual airspeed. This error in the pitot pressure sensor will result in a lower indicated airspeed than actual airspeed. The error in the pressure sensor measurement is a result of a leak within the pressure sensor's vacuum reference that is compared with the actual applied pressure. This condition, if not corrected, could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. Relevant Service Information We reviewed Honeywell Alert Service Bulletin ADM/ADC/ADAHRS-34-A01, dated November 6, This service bulletin describes procedures for an indicated altitude test of equipment (i.e., air data modules (ADM), air data computers, air data attitude heading reference systems, and digital air 2
3 data computers) having certain air data pressure transducers, repetitive pressure sensor tests if necessary, and removal of equipment if necessary. This service bulletin also specifies optional actions, including repetitive pitot-static certification testing and removal of equipment having certain air data pressure transducers. We have also reviewed Airbus Alert Operators Transmission (AOT) A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A318/A319/A320/A321 series airplanes; and Airbus AOT A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A330 series airplanes. These AOTs describe procedures for doing a repetitive ADM check or a functional test of the ADM accuracy, and replacing the ADM if necessary. FAA's Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. AD Requirements This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ''Differences Between the AD and the Service Information.'' The AD also requires sending the test or check results (both pass and fail) to the FAA and Honeywell. Differences Between the AD and the Service Information The service information that follows specifies certain corrective actions for various conditions. However we differ from these actions and conditions in that this AD requires removing affected equipment and returning the equipment to Honeywell if those conditions are found. Airbus Alert Operators Transmission (AOT) A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A318/A319/A320/A321 series airplanes; and Airbus AOT A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A330 series airplanes; specifies to replace the ADM if the ADM check fails. Honeywell Service Bulletin ACM/ADC/ADAHRS-34-A01, dated November 6, 2012, specifies to refer to ''applicable procedures'' if the indicated altitude test exceeds 75 feet (23 meters). Honeywell Service Bulletin ACM/ADC/ADAHRS-34-A01, dated November 6, 2012, specifies to remove the affected equipment if the pressure test is greater than 0.70 millibar (mb). In addition, the service information that follows is missing corrective actions for certain conditions; however, this AD requires removing affected equipment and returning the equipment to Honeywell for those conditions that are missing corrective actions. Airbus Alert Operators Transmission (AOT) A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A318/A319/A320/A321 series airplanes; and Airbus AOT A34N001-12, including Appendices A and B, dated November 15, 2012, for Airbus Model A330 series airplanes; does not specify any corrective action if the functional test of the ADM accuracy fails. Honeywell Service Bulletin ACM/ADC/ADAHRS-34-A01, dated November 6, 2012, does not specify any corrective action if the pitot static certification test fails. 3
4 Interim Action We consider this AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. FAA's Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because inaccuracies of the pressure sensors could result in altitude, computed airspeed, true airspeed, and Mach computation errors. These errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA and Directorate Identifier 2012-NM-191-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 90 appliances installed on, but not limited to, various aircraft of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs Action Labor cost Parts cost Cost per product Cost on U.S. operators Indicated altitude test 2 work-hours $85 per hour = $170 $0 $170 Up to $15,300. Removal 2 work-hours $85 per hour = $ Up to $15,300. Pitot static certification test 3 work-hours $85 per hour = $ Up to $22,950. ADM check or test 2 work-hours $85 per hour = $ Up to $15,300. We estimate the following costs to do any necessary pressure sensor tests or removals that would be required based on the results of the tests or checks. We have no way of determining the number of aircraft that might need these pressure sensor tests or removals: 4
5 On-Condition Costs Action Labor cost Parts cost Cost per product Pressure sensor test 2 work-hours $85 per hour = $170 $0 $170 Removal 2 work-hours $85 per hour = $ 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 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) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) 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.
