TM   1-1500-250-23 (4)  Connect  two  crossing  chain  assemblies  diago- nally  from  the  aft  aircraft  landing  gear  mooring  rings  to  the rear  mooring  pad  points. (5) Connect two side chain assemblies from the aft aircraft landing gear mooring rings to the rear mooring pad points. (6) Tighten the MB-1 adjusters to remove the slack from all mooring chains. Not ools are required. c. UH-60 Helicopter Morning Procedures. (1) Position the aircraft on the mooring pad with the longitudinal centerline of the aircraft directly above and parallel to the longitudinal axis of the pad as shown in fig- ures 4-8, 4-8a, 4-8b, 4-8c and 4-8d. Figures 4-8, 4-8c and 4-8d are to be used for aircraft that do not have external tanks installed Figure 4-8a is to be used when aircraft have external tanks installed. Figure 4-8b is to be used for the EH-60   aircraft. (2) For mooring of the UH-60 per figure 4-8: (a) Position the aircraft front rooming rings di- rectly  in-line  with  the  front  mooring  pad  points. (b) Connect two chain assemblies from the for- ward aircraft mooring rings at F.S. 308 to the front rooming pad  points. (c)  Connect  two  chain  assemblies  from  the  front mooring pad points to the aft aircraft mooring rings at F.S. 485. (d)  Connect  two  chain  assemblies  from  the  aft  air- craft mooring rings to the center rooming pad points. (e) Tighten the MB-1 chain adjusters to remove the slack from all mooring chains. No tools are required. (3) For mooring the UH-60 per figure 4-8a: (a) Position the aircraft cargo hook directly in- line with the center mooring pad points. (b) Connect two lateral chain assemblies from the aircraft cargo hook to the center mooring pad ponts (Ref. figure 4-8, view A-A). (c) Connect two chain assemblies from the center mooring pad points to the aft aircraft mooring rings at F.S. 485. (d)  Connect  two  chain  assemblies  from  the  aft  air- craft mooring rings to the rear mooring pad points. (e)  Tighten  the  MB-1  chain  adjusters  to  remove the  slack  from  all  mooring  chains.  No  tools  are  required. (4) For mooring the EH-60 per figure 4-8b: (a) Position the aircraft front rooming rings di- rectly in-line with the front mooring pad points. (b) Connect two chain assemblies from the for- ward aircraft mooring rings at F.S. 308 to the front mooring pad  points. (c) Connect two chain assemblies from the center mooring  pad  points  to  the  forward  aircraft  rooming  rings  at F.S. 308. (d) Connect two chain assemblies from the aft air- craft mooring rings at F.S. 485 to the center mooring pad points. (e)  Tighten  the  MB-1  chain  adjusters  to  remove the  slack  from  all  mooring  chains.  No  tools  are  required. (5)  For  alternate  rooming  of  UH-60  per  figure  4-8c: (a) Position the aircraft front mooring rings di- rectly in-line with the center mooting pad points as shown in figure 4-8C. (b) Connect two chain assemblies from the for- ward aircraft mooriing rings at F.S. 308 to center mooring pad points as shown in figure 4-8c. (C)  Connect  two  chain  assemblies  from  the  center mooring  pad  points  to  the  aft  aircraft  mooring  rings  at  F.S. 485 as shown in figure 4-8c. (d)  Connect  two  chain  assemblies  from  the  aft  air- craft rooming rings at F.S. 485 to the rear mooring pad points as shown in figure 4-8C. (e) Tighten the MB-l chain adjusters to remove the slack from all mooring chains. No tools are requiredl. (6) For alternate rooming UH-60 per figure 4-8d. (a) Position the aircraft on the mooring pad with longitudinal  centerline  of  the  aircraft  directly  above  and parallel to the longitudinal axis of the pad as shown in figure 4-8d. Position the aircraft front mooring rings, at F.S. 308. 10 feet aft of the forward mooring pad points as shown in figure 4-8d. (b) Connect two chain assemblies from the front mooring rings at F.S. 308 to the forward mooring pad points as shown in figure 4-8d. (c) Connect two chain assemblies from the front mooring  rings  at  F.S.  308  to  the  center  mooring  pad  points as shown in figure 4-8d. (d) Connect two chain assemblies from the aft air- craft mooring rings at F.S. 308 to the center mooring pad points as shown in figure 4-8d. (e) Connect two chain assemblies from the air- craft mooring rings at F.S. 485 to the rear rooming pad points. (f)  Tighten  the  MB-1  chain  adjusters  to  remove the slack from all mooring chains. No tools arm required. d.  AH-1  Helicopter  Mooring  Procedures. (1)  Position  aircraft  on  mooring  pad  with  longitudi- nal centerline of aircraft directly above and parallel to the longitudinal axis of pad, shown in figure 4-9. The aft moor- ing ring is to be located 2 feet forward of the center mooring pad points. 4-2      Change 3
