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.
All models on A20EA: DHC-7-1, DHC-7-100, DHC-7-101, DHC-7-102 and DHC-7-103.
The listed holder changes from Viking Air Limited, 9574 Hampden Road, Sidney, British Columbia, Canada V8L 5V5, to De Havilland Aircraft of Canada Limited, 4100 Westwinds Drive NE, Calgary, Alberta, Canada T3J 4L2. Viking Air Limited is moved into the Type Certificate Holder Record, which continues to list Bombardier Inc., Regional Aircraft.

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.
