Dave Scott’s lunar-flown ring-bound “LM Malfunction Procedures” manual used on the surface of the moon during the Apollo 15 mission. The manual, 8.5 x 10.5, 96 pages, is signed and flight-certified on the front cover in blue felt tip, "Flown to the lunar surface aboard the Lunar Module ‘Falcon’ during Apollo 15, July 26-Aug 7, 1971, Dave Scott, Apollo 15 CDR." The cover is marked "Apollo 15, LM Malfunction Procedures, Part No. SKB32100116-386, S/N 1001," with the edge of the manual marked “MALF,” to facilitate retrieval amongst other similar documents. The manual is comprised of identification and correction actions for each major system of the lunar module. In addition to systems like the Reaction Control System (RCS), the Ascent Propulsion System (APS), and the Guidance and Control Displays (G&C Displays), the manual also contains malfunction procedures for the Lunar Riving Vehicle (LRV) and the Hasselbald camera used on the lunar surface, with each section tabbed for the corresponding system or component. In fine condition. Accompanied by a signed letter of provenance from Scott, in part: “I hereby certify that the ‘LM Malfunction Procedures’ book included with this letter was used on the lunar surface for three days during the first extended scientific exploration of the Moon at the Hadley Apennine region during Apollo 15, July 26-August 7, 1971…As the mission commander of Apollo 15, I was in charge of the handling, use and dissemination of the Flight Date File (FDF), as such, this ‘LM Malfunction Procedures’ book has been in my personal collection since NASA presented it to me upon our return to Earth."
Aside from a lunar drilling problem and a faulty Service Propulsion System light, the Apollo 15 mission was remarkably issue-free for the first scheduled 'J' mission, and has long been considered one of the most successful excursions of the Apollo program. Over the course of twelve days, the Apollo 15 crew explored the Hadley-Apennine region, set up and activated lunar surface scientific experiments, made engineering evaluations of new Apollo equipment, and conducted lunar orbital experiments and photographic tasks. Additionally, the Apollo 15 mission set several new records, including: heaviest payload in a lunar orbit of approximately 107,000 pounds; maximum radial distance traveled on the lunar surface away from the spacecraft of about 17.5 miles; most lunar surface EVAs with three, and longest total of duration for lunar surface EVAs (18 hours, 37 minutes); longest time spent in lunar orbit (about 145 hours); longest Apollo mission (295 hours); the first satellite placed in lunar orbit by a crewed spacecraft (a Particles and Fields subsatellite); and first deep space and operational EVA, conducted by CMP Al Worden on August 5th. A remarkable lunar surface-flown manual back by provenance direct from the mission commander. From the personal collection of Dave Scott.
