Segelflugzeugbau (Alexander Schleicher) applied for validation of a type certificate change to add the Model ASK 21 B glider in accordance with the ‘‘Technical Implementation Procedures for Airworthiness and Environmental Certification Between the FAA and the European Aviation Safety Agency (EASA),’’ Revision 6, dated September 22, 2017. This model is a modified version of the Model ASK 21 glider and will be documented on existing Type Certificate Number (No.) G47EU. The Model ASK 21 B is a two-seat, mid-wing glider constructed from glass-fiber reinforced plastic and features a 55.8 foot (17 meters) wingspan with airbrakes on the upper wing surface. The glider has a non-retractable landing gear with a nose wheel and shockabsorbed, braked main wheel and a Ttype tailplane. The glider has a maximum weight of 1,323 pounds (600 kilograms). EASA type certificated the Model ASK 21 B glider in the utility and aerobatic categories and issued Type Certificate No. EASA.A.221, dated August 9, 2018. The associated EASA Type Certificate Data Sheet (TCDS) No. EASA.A.221 defined the certification basis, which Alexander Schleicher submitted to the FAA for review and acceptance. Gliders are type certificated by the FAA as special class aircraft for which airworthiness standards have not yet been established by regulation. Under the provisions of 14 CFR 21.17(b), the airworthiness standards for special class aircraft are those found by the FAA to be appropriate and applicable to the specific type design. FAA Advisory Circular (AC) 21.17–2A 1 provides guidance on acceptable design criteria for the type certification of gliders and powered gliders in the United States. AC 21.17–2A allows applicants to utilize the Joint Aviation Requirements (JAR)-22 2, other airworthiness criteria comparable to 14 CFR part 23, or a combination of both as the means for showing compliance for glider certification. Type Certification Basis The certification basis for the Model ASK 21 B will be the same as the certification basis for the Model ASK 21 as shown on TCDS No. G47EU, Revision 1 Ref AC 21.17–2A, ‘‘Type Certification—FixedWing Gliders (Sailplanes), Including Powered Gliders,’’ dated February 10, 1993. 2 Ref JAR–22, ‘‘Sailplanes and Powered Sailplanes.’’ E:\FR\FM\02APP1.SGM 02APP1 12530 Federal Register / Vol. 84, No. 63 / Tuesday, April 2, 2019 / Proposed Rules 1, except for areas affected by the change, which will use EASA Certification Specification (CS)-223 as shown in these proposed airworthiness criteria.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period. AGENCY: We are revising an earlier proposal for certain Gulfstream Aerospace Corporation (Gulfstream) Model G–IV and Model GIV–X airplanes.

We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes.

Background

    On August 16, 2018, Alexander Schleicher GmbH & Co. 
Segelflugzeugbau (Alexander Schleicher) applied for validation of a 
type certificate change to add the Model ASK 21 B glider in accordance 
with the ``Technical Implementation Procedures for Airworthiness and 
Environmental Certification Between the FAA and the European Aviation 
Safety Agency (EASA),'' Revision 6, dated September 22, 2017. This 
model is a modified version of the Model ASK 21 glider and will be 
documented on existing Type Certificate Number (No.) G47EU. The Model 
ASK 21 B is a two-seat, mid-wing glider constructed from glass-fiber 
reinforced plastic and features a 55.8 foot (17 meters) wingspan with 
airbrakes on the upper wing surface. The glider has a non-retractable 
landing gear with a nose wheel and shock-absorbed, braked main wheel 
and a T-type tailplane. The glider has a maximum weight of 1,323 pounds 
(600 kilograms).
    EASA type certificated the Model ASK 21 B glider in the utility and 
aerobatic categories and issued Type Certificate No. EASA.A.221, dated 
August 9, 2018. The associated EASA Type Certificate Data Sheet (TCDS) 
No. EASA.A.221 defined the certification basis, which Alexander 
Schleicher submitted to the FAA for review and acceptance.
    Gliders are type certificated by the FAA as special class aircraft 
for which airworthiness standards have not yet been established by 
regulation. Under the provisions of 14 CFR 21.17(b), the airworthiness 
standards for special class aircraft are those found by the FAA to be 
appropriate and applicable to the specific type design. FAA Advisory 
Circular (AC) 21.17-2A \1\ provides guidance on acceptable design 
criteria for the type certification of gliders and powered gliders in 
the United States. AC 21.17-2A allows applicants to utilize the Joint 
Aviation Requirements (JAR)-22 \2\, other airworthiness criteria 
comparable to 14 CFR part 23, or a combination of both as the means for 
showing compliance for glider certification.
