Blackburn Bluebird IV
type of aircraft

The Blackburn Bluebird IV was a single-engine biplane light trainer/tourer biplane with side-by-side seating designed by the British aviation manufacturer Blackburn Aircraft. It was an all-metal development of the wooden Blackburn Bluebird I, II and III aircraft.
The Blackburn IV was developed as a refinement of the preceding members of the Bluebird series; in addition to its all-metal airframe, it was noticeably more streamlined and its structure was simplified as to more readily facilitate its construction. Individual areas such as the tail unit and undercarriage were extensively revised. Conventional controls were used wherever practical. The Bluebird IV was a larger and heavier aircraft than its predecessors and could be fitted with various engines as standard, such as the de Havilland Gipsy, ADC Cirrus, and Cirrus Hermes. The first prototype performed its maiden flight on 23 February 1929. One month prior to the first flight, the prototype Bluebird IV had already been sold to a private owner that, only two weeks following, undertook a five-week long-distance journey to South Africa with it.
Due to a lack of capacity, Blackburn did not proceed with quantity manufacture of the type in-house; instead, this work was outsourced to other aviation companies. Saunders-Roe was subcontracted to construct the Bluebird IV, building 55 aircraft between late 1929 and May 1931.
This brief starts where responsible research should: with the source description of “Blackburn Bluebird IV” as type of aircraft. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as type of aircraft. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 13, 2025. The linked authority identifier is Q4922659. The first chronological checks are 1929 and 1931.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
