Amdt 1

Bulkhead Smoke Seal 12/93

Applicability: Model DHC-8 series 100A aircraft with serial numbers 191 and 225 through 307. Requirement: Install close out block seals in accordance with de Havilland SB 8-25-80 Rev A.

Note: Transport Canada AD CF-92-16 refers.

Compliance: Unless already accomplished in accordance with the previous issue of the Requirement Document; prior to 11 March 1994.

Background: During the introduction of furnishing improvements by the manufacturer, close out block seals on the cabin/baggage compartment bulkhead were omitted on some aircraft. With no block seals installed, a direct smoke path exists between the baggage compartment and the cabin.

Amendment 1 is issued in response to a revision of the Requirement Document which expands applicability and adds an inspection requirement.
