DOCKED APS BURN.
Flown on Apollo 13, LM-7 Contingency Checklist, pp. 20 and 21. A single sheet printed recto and verso. NASA/MSC January 6, 1970, updated February 9, 1970. 8 x 5½ inches. With a Typed Letter Signed by FRED HAISE.

The crew of Apollo 13 successfully used their Lunar Module descent engine to safely return them to Earth. If that engine had not had sufficient fuel or thrust to completely make the return trip, then the ascent stage engine would have been employed to make up the difference. Astronaut Haise indicated while writing the letter for this artifact that if indeed the APS had been need for the return home, it would have been the most demanding flight scenario ever imagined for Apollo and he was glad that they did not have to employ these steps to return home.
FRED HAISE'S September 20, 2007 signed provenance letter reads in part: "Accompanying this letter is a sheet numbered 20 and 21 from the Apollo 13 LM-7 Contingency Checklist carried and used on the flight of Apollo 13 during April 11 to 17, 1970. Our flight was scheduled to be the third lunar landing mission but had to be aborted after a Service Module oxygen tank explosion. During this emergency, electrical power conservation was paramount in order for us to survive the amount of time required to return to the Earth. Commander Jim Lovell would have used this sheet to perform any LM Ascent Propulsion System burns to get our crippled CSM and docked LM back to Earth if our LM descent engine failed.
The top of side 20 is labeled
'DOCKED APS BURN' and would be used primarily for an abort during insertion into lunar orbit if our descent engine did not provide sufficient velocity to escape from the lunar gravity environment. The center of this side has an illustration of our FDAI or Flight Director Attitude Indicator on the LM control panel. It also describes the flight method for 'PITCH Error' then 'ROLL Needle Left' with steps I should perform immediately after APS ignition. I made the additional notes in red ink of: 'If rate & err needles moving in same direction in same quadrant.'
The side numbered 21 has a series of steps including battery, circuit breaker, and switch settings. Various systems were set to
'ON' or 'OFF' with some 'OPEN' or 'CLOSED.' The steps after '400+5' were to load and verify the actual burn values including time and attitude.
After the flight I wrote and signed side 20 and 21 in blue ink with:
'Carried around the Moon! Fred Haise, Apollo 13 LMP.' This sheet has been in my personal collection since 1970. It is a significant artifact from the Apollo 13 mission."
