LAF Tower Controller reported the lack of an operational crash phone hinders the ability to contact first responders as highlighted by a recent aircraft loss of power incident.

Narrative

Aircraft X was in the pattern for runway 10 along with a few other aircraft and after his last touch and go reported loss of power over the departure end runway 10. Runway 23 was immediately offered to the pilot reference their altitude and position over the field. The pilot stated that they could accept Runway 23 and was cleared to land. As the pilot began to make the turn for runway 23; they advised that they were getting partial power back but was unable to align safely with runway 23 and would prefer runway 28. Aircraft X was then cleared to land runway 28 opposite direction and issued the current winds. Because Aircraft X was landing opposite direction to all other traffic two aircraft were sent around on runway 10. Aircraft Y was sent around at about a mile final runway 10 as well as Aircraft Z on about a 2 mile final. Aircraft X was able to safely land runway 28 and exit at taxiway Charlie 2. Aircraft X was also able to successfully taxi back to parking via taxiways Charlie; Bravo; and Delta. Currently there is no crash phone at LAF and given the situation of unexpected opposite direction operations; my first intention was to clear all other aircraft out of the way for Aircraft X in distress. Once all potential conflicts were tended to; Aircraft X successfully landed the aircraft and said that they did not require any further assistance. All of the necessary paperwork and point of contacts were notified in a timely manner. Had there been an operational crash phone available in the cab; I would have been able to quickly and promptly call both the police and fire department while continuing to work simultaneously. Luckily they were not needed and people are property were protected. I think LAF should be provided an operational crash phone asap for potential events similar to this one. Again; luckily everything worked out fine but if it had been an inexperienced pilot operating Aircraft X that aircraft could have easily ended up landing in the grass or on a non movement area. Being able to continue to work and simultaneously talk to the proper authorities is huge when dealing with low altitude and spontaneous situations taking place directly at the field.
