The '''Beechcraft Model 38P Lightning''' was an experimental [turboprop](/source/turboprop) aircraft built and tested by [Beechcraft](/source/Beechcraft) in the 1980s.

== History ==
The Model 38P ('''P'''ressurized) (also known as the model PD.336) was created by installing a [Garrett AiResearch TPE-331](/source/Garrett_AiResearch_TPE-331)-9 engine in the nose of a [Beechcraft Baron 58P](/source/Beechcraft_Baron) fuselage, which was mated to a [Beechcraft B36TC Bonanza](/source/Beechcraft_Bonanza) wing in place of the Baron's wing with two engines.<ref name="BP"/> This resulted in a low-wing aircraft with six seats including the pilot's. The aircraft flew for the first time on June 14, 1982.<ref name="BP"/> After 133 flights over almost 18 months the aircraft was temporarily grounded so that the TPE331 could be removed and a [Pratt & Whitney Canada PT6](/source/Pratt_%26_Whitney_Canada_PT6)A-40 engine fitted in its place.<ref name="BP"/> The aircraft flew in this configuration for the first time on March 9, 1984 and the last flight was on August 8 the same year.<ref name="BP"/> Beechcraft originally planned to put the Lightning into production but the economic downturn among [general aviation](/source/general_aviation) manufacturers in the [United States](/source/United_States) in the 1980s led to the project being shelved<ref>[http://www.wingsoverkansas.com/murphy/article.asp?id=645 "The Beeches that got away", Wings Over Kansas website] {{Webarchive|url=https://web.archive.org/web/20130407111201/http://www.wingsoverkansas.com/murphy/article.asp?id=645 |date=April 7, 2013 }} retrieved December 20, 2007.</ref> shortly after the first flight with PT6A power.<ref name="BP">[Phillips, Edward H.](/source/Edward_H._Phillips), ''Beechcraft - Pursuit of Perfection, A History of Beechcraft Airplanes''.

== Variants ==

:One prototype modified from a Model 58P Baron with a [Garrett AiResearch TPE-331](/source/Garrett_AiResearch_TPE-331)-9.  Plans to produce the 38P with a [Pratt & Whitney Canada PT6A-40](/source/Pratt_%26_Whitney_Canada_PT6) were abandoned.<ref name="Pelletier"/>
