Discussion

    Elsewhere in this Federal Register, we invite public comment on a 
notice of proposed rulemaking (NPRM) concerning the material strength 
properties and material design values requirements for transport 
category airplanes. The proposed rule would reinstate a provision that 
permits the Administrator to approve other material design values 
published in accepted military and industry handbooks. Additionally, 
other changes of a clarifying nature are proposed. These proposed 
revisions are intended to achieve common requirements and language 
between the requirements of the U.S. regulations and the Joint Aviation 
Requirements of Europe.
    In addition to the amendments proposed in the NPRM, we announced 
the development of advisory material to supplement the proposal. The 
proposed advisory material describes acceptable methods of compliance 
with the proposed rule, and is intended to be reviewed along with the 
NPRM.

    Issued in Renton, WA, on January 8, 2002.
Ali Bahrami,
Acting Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
