I don't have any definitive citation, but James Briggs from Sheffield
Hallam University posted the following:
To go pear shaped is an expression used to indicate that a scheme has not
been perfectly executed. The phrase seems to have originated in British
English in the late 1940s or early 1950s. 1 have come across several
suggested origins, but the best, for me, is related to training aircraft
pilots. At some stage they are encouraged to try to fly loops - very
difficult to make perfectly circular; often the trainee pilot's loops
would go pear shaped.
The same origin is referred to in
That such a phrase is so popular, without any definitive origin, suggests
that it holds some resonance in its own right. I think the evocative idea
of a pure circle sagging out of shape to become pear-shaped is sufficient to
explain the popularity of the phrase, if not the origin.
