AT A GLANCE

Revision 6 replaces Viking Air Limited with De Havilland Aircraft of Canada Limited as the type certificate holder and moves Viking into the holder record. The extracted 25,000-ft operating-altitude provision contains damaged wording whose significance cannot be confirmed from the supplied evidence. Otherwise, the aircraft limitations, configurations, approved-publication references, certification basis and notes remain unchanged; the document is repaginated from six pages to five.

Uncertain text damage in altitude provision

DHC-7-1, DHC-7-100, DHC-7-101, DHC-7-102 and DHC-7-103; the common maximum operating-altitude provision.

Revision 6's extracted text reads “breathing e uipment is provid d” where Revision 5 reads “breathing equipment is provided.” The 25,000-ft value and reference to all occupants remain present, and the adjacent 20,400-ft limitation referencing FAR 25.841(a) is unchanged. The supplied evidence does not establish whether the missing letters are a source-document defect or an extraction artifact; this is not treated as a confirmed change to the operating limitation.

REVISION 5 · BEFORE

25,000 ft. (when supplementary breathing equipment is provided for all occupants).

Revision 5, page 5 ↗

REVISION 6 · AFTER
