This is a pilotselectable function that allows earlier maximum braking at landing without pilot pedal input. When the autobrake system is armed before landing, it automatically commands maximum braking at main wheels touchdown. Normal procedures remain unchanged VerDate Nov<24>2008 16:49 Dec 09, 2009 Jkt 220001 and call for manual braking after nose wheel touchdown. The current Federal Aviation Regulations do not contain adequate requirements to address the potentially higher structural loads that could result from this type of automatic braking system. Title 14, Code of Federal Regulations (14 CFR) 25.471 through 25.511 address ground handling loads, but do not contain a specific ‘‘pitchover’’ requirement addressing the loading on the nose gear, the nose gear surrounding structure, and the forward fuselage. The Dassault autobraking system, which applies maximum braking at the main wheels before the nose gear touches down, will cause a high nose gear sink rate, and potentially higher gear and airframe loads. Therefore, the FAA has determined that a special condition is needed. The special condition requires that the airplane be designed to withstand the loads resulting from maximum braking, taking into account the effects of the automatic braking system. Type Certification Basis Under the provisions of § 21.101, Dassault Aviation must show that the Falcon Model 2000EX, as changed, continues to meet the applicable provisions of the regulations incorporated by reference in TC No. A50NM, or the applicable regulations in effect on the date of application for the change. The regulations incorporated by reference in the type certificate are commonly referred to as the ‘‘original type certification basis.’’ The regulations incorporated by reference in TC No. A50NM are as follows: Title 14 Code of Federal Regulations (14 CFR) part 25 as amended by Amendments 25–1 through 25–69. In addition, Dassault Aviation has elected to comply with the following amendments: • Amendment 25–71 for § 25.365(e); • Amendment 25–72 for §§ 25.783(g) and 25.177; • Amendment 25–75 for § 25.729(e); • Amendment 25–79 for § 25.811(e)(2); • Amendment 25–80 for § 25.1316. In addition, the certification basis includes certain special conditions, exemptions, or later amended sections of the applicable part that are not relevant to this proposed special condition. If the Administrator finds that the applicable airworthiness regulations (i.e., part 25) do not contain adequate or appropriate safety standards for the Falcon Model 2000EX because of a novel or unusual design feature, special PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 65395 conditions are prescribed under the provisions of § 21.16. In addition to the applicable airworthiness regulations and special conditions, the Falcon Model 2000EX must comply with the fuel vent and exhaust emission requirements of 14 CFR part 34 and the noise certification requirements of 14 CFR part 36. The FAA issues special conditions, as defined in §§ 11.19 and 11.38, and they become part of the type-certification basis under § 21.101. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same or similar novel or unusual design feature, or should any other model already included on the same type certificate be modified to incorporate the same or similar novel or unusual design feature, the special conditions would also apply to the other model under § 21.101. Novel or Unusual Design Features The Falcon Model 2000EX will incorporate the following novel or unusual design features: The airplane will be equipped with an automatic braking system, which is a pilot-selectable function that allows earlier maximum braking at landing without pilot pedal input. When the autobrake system is armed before landing, it automatically commands maximum braking at main wheels touchdown. This will cause a high nose gear sink rate, and potentially higher gear and airframe loads than would occur with a traditional braking system. Therefore, the FAA has determined that a special condition is needed. Discussion The special condition defines a landing pitchover condition that takes into account the effects of the automatic braking system. The special condition defines the airplane configuration, speeds, and other parameters necessary to develop airframe and nose gear loads for this condition. The special condition requires that the airplane be designed to support the resulting limit and ultimate loads as defined in § 25.305. Applicability As discussed above, these special conditions are applicable to the Falcon Model 2000EX. Should Dassault Aviation apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, the special conditions would apply to that model as well.

The Proposed Special Condition Accordingly, the Federal Aviation Administration (FAA) proposes the following special condition as part of the type certification basis for Dassault Aviation Falcon Model 2000EX airplanes. ■ AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. Landing Pitchover Condition A landing pitchover condition must be addressed that takes into account the effect of the autobrake system. The airplane is assumed to be at the design maximum landing weight, or at the maximum weight allowed with the autobrake system on. The airplane is assumed to land in a tail-down attitude and at the speeds defined in § 25.481. Following main gear contact, the airplane is assumed to rotate about the main gear wheels at the highest pitch rate allowed by the autobrake system. This is considered a limit load condition from which ultimate loads must also be determined. Loads must be determined for critical fuel and payload distributions and centers of gravity. Nose gear loads, as well as airframe loads, must be determined. The airplane must support these loads as described in § 25.305. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 772 B engines experienced an engine#1 uncontained multiple turbine blade failure. Investigations have shown that High Pressure/Intermediate Pressure (HP/IP) oil vent tubes are prone to be affected by carbon deposit or to be damaged by their outer heat shields leading to a fire inside or outside the vent tube and resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT disc overspeed. If not corrected, IPT disc overspeed could lead to an uncontained engine failure, i.e. multiple turbine blade failure or HP/IP turbine disc burst, which would constitute an unsafe condition.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009–0075, dated April 6, 2009 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 772 B engines experienced an engine#1 uncontained multiple turbine blade failure. Investigations have shown that High Pressure/Intermediate Pressure (HP/IP) oil vent tubes are prone to be affected by carbon deposit or to be damaged by their outer heat shields leading to a fire inside or outside the vent tube and resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT disc overspeed. If not corrected, IPT disc overspeed could lead to an uncontained engine failure, i.e. multiple turbine blade failure or HP/IP turbine disc burst, which would constitute an unsafe condition. In order to protect IPT from overspeed, EASA AD 2008–0101 required to activate Intermediate Pressure Turbine Overspeed (IPTOS) protection function by Data Entry Plug (DEP) reprogramming, which consists in limiting the IPT speed (Engine Thrust) when overheat is detected in IPT, for all A330 aeroplanes fitted with RR Trent 700 engines and equipped with Multi Mode Receivers. Original issue of AD 2008–0101 had a limited applicability due to Flight Warning Computer compatibility issue with aircraft not equipped with Multi Mode Receivers.

Background

    On July 1, 2008, Dassault Aviation applied for a change to Type 
Certificate (TC) No. A50NM to install an automatic braking system in 
the Falcon Model 2000EX airplane. This is a pilot-selectable function 
that allows earlier maximum braking at landing without pilot pedal 
input. When the autobrake system is armed before landing, it 
automatically commands maximum braking at main wheels touchdown. Normal 
procedures remain unchanged and call for manual braking after nose 
wheel touchdown.
    The current Federal Aviation Regulations do not contain adequate 
requirements to address the potentially higher structural loads that 
could result from this type of automatic braking system. Title 14, Code 
of Federal Regulations (14 CFR) 25.471 through 25.511 address ground 
handling loads, but do not contain a specific ``pitchover'' requirement 
addressing the loading on the nose gear, the nose gear surrounding 
structure, and the forward fuselage. The Dassault autobraking system, 
which applies maximum braking at the main wheels before the nose gear 
touches down, will cause a high nose gear sink rate, and potentially 
higher gear and airframe loads. Therefore, the FAA has determined that 
a special condition is needed. The special condition requires that the 
airplane be designed to withstand the loads resulting from maximum 
braking, taking into account the effects of the automatic braking 
system.

Type Certification Basis

    Under the provisions of Sec.  21.101, Dassault Aviation must show 
that the Falcon Model 2000EX, as changed, continues to meet the 
applicable provisions of the regulations incorporated by reference in 
TC No. A50NM, or the applicable regulations in effect on the date of 
application for the change. The regulations incorporated by reference 
in the type certificate are commonly referred to as the ``original type 
certification basis.'' The regulations incorporated by reference in TC 
No. A50NM are as follows:
    Title 14 Code of Federal Regulations (14 CFR) part 25 as amended by 
Amendments 25-1 through 25-69. In addition, Dassault Aviation has 
elected to comply with the following amendments:
     Amendment 25-71 for Sec.  25.365(e);
     Amendment 25-72 for Sec. Sec.  25.783(g) and 25.177;
     Amendment 25-75 for Sec.  25.729(e);
     Amendment 25-79 for Sec.  25.811(e)(2);
     Amendment 25-80 for Sec.  25.1316.
    In addition, the certification basis includes certain special 
conditions, exemptions, or later amended sections of the applicable 
part that are not relevant to this proposed special condition.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., part 25) do not contain adequate or appropriate 
safety standards for the Falcon Model 2000EX because of a novel or 
unusual design feature, special conditions are prescribed under the 
provisions of Sec.  21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the Falcon Model 2000EX must comply with the fuel vent and 
exhaust emission requirements of 14 CFR part 34 and the noise 
certification requirements of 14 CFR part 36.
    The FAA issues special conditions, as defined in Sec. Sec.  11.19 
and 11.38, and they become part of the type-certification basis under 
Sec.  21.101.
    Special conditions are initially applicable to the model for which 
they are issued. Should the type certificate for that model be amended 
later to include any other model that incorporates the same or similar 
novel or unusual design feature, or should any other model already 
included on the same type certificate be modified to incorporate the 
same or similar novel or unusual design feature, the special conditions 
would also apply to the other model under Sec.  21.101.

Novel or Unusual Design Features

    The Falcon Model 2000EX will incorporate the following novel or 
unusual design features:
    The airplane will be equipped with an automatic braking system, 
which is a pilot-selectable function that allows earlier maximum 
braking at landing without pilot pedal input. When the autobrake system 
is armed before landing, it automatically commands maximum braking at 
main wheels touchdown. This will cause a high nose gear sink rate, and 
potentially higher gear and airframe loads than would occur with a 
traditional braking system. Therefore, the FAA has determined that a 
special condition is needed.

Discussion

    The special condition defines a landing pitchover condition that 
takes into account the effects of the automatic braking system. The 
special condition defines the airplane configuration, speeds, and other 
parameters necessary to develop airframe and nose gear loads for this 
condition. The special condition requires that the airplane be designed 
to support the resulting limit and ultimate loads as defined in Sec.  
25.305.

Applicability

    As discussed above, these special conditions are applicable to the 
Falcon Model 2000EX. Should Dassault Aviation apply at a later date for 
a change to the type certificate to include another model incorporating 
the same novel or unusual design feature, the special conditions would 
apply to that model as well.

[[Page 65396]]

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplanes. It is not a rule of general applicability.

    Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

The Proposed Special Condition

0
Accordingly, the Federal Aviation Administration (FAA) proposes the 
following special condition as part of the type certification basis for 
Dassault Aviation Falcon Model 2000EX airplanes.

Landing Pitchover Condition

    A landing pitchover condition must be addressed that takes into 
account the effect of the autobrake system. The airplane is assumed to 
be at the design maximum landing weight, or at the maximum weight 
allowed with the autobrake system on. The airplane is assumed to land 
in a tail-down attitude and at the speeds defined in Sec.  25.481. 
Following main gear contact, the airplane is assumed to rotate about 
the main gear wheels at the highest pitch rate allowed by the autobrake 
system. This is considered a limit load condition from which ultimate 
loads must also be determined. Loads must be determined for critical 
fuel and payload distributions and centers of gravity. Nose gear loads,
