*Service Documents identified by an asterisk and by (a) have been revised subsequent to issuance of AD-763 (Special) dated Aug. 21, 1946, as indicated by the later revision date effective in each instance. Aircraft previously recertificated in accordance with AD-763 (Special) should be checked for compliance with these later revisions within next 200 hours of operations.

**Service Bulletin 49/SB-161 was not called for in AD-763 (Special), but has subsequently been found necessary, inasmuch as Bulletin 49/SB-123 does not adequately describe changes to 2-pump anti-icing systems. Aircraft incorporating 2-pump anti-icing systems should be checked for conformity with Bulletin 49/SB-161 prior to certification.
