Source-derived summary

The Pitcairn Mailwing family is a series of American mail carrier and three-seat sport utility biplane aircraft produced from 1927 to 1931.

Design and development

The Pitcairn Mailwings were developed to carry air mail for the United States Post Office Department. Of simple and robust construction, they had relatively benign flying characteristics.

They were constructed using chrome-moly steel tube and square-section spruce spars with spruce and plywood built-up ribs. The fuselage was faired using wooden formers and covered with fabric. The tail sections were built up from steel tube and fabric-covered. The Pitcairn Mailwing had a ground-adjustable fin and in-flight adjustable tailplane.

The undercarriage was of outrigger type with Oleo-Spring shock absorbers and disc brakes on the mainwheels. All versions looked very similar and changes were minor, with several fuselage extensions being the most obvious.

The mail was carried in a fireproof metal-lined compartment forward of the pilot's cockpit.

The account is most persuasive where Pitcairn, Mailwing and mailplane can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 1927 mailplane family by Pitcairn. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q2533014. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1927 and 1931.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
