EMB 505 Captain reports an emergency landing due to hydraulic failure which results in a blown main tire. In the aftermath the aircraft log is completely overlooked and no discrepancy is entered. This oversight is not detected until six days later.

Narrative

After an emergency landing due to a complete hydraulic failure; I was escorted from the aircraft before noting the malfunction in the aircraft discrepancy log. Prior to the landing; I had been in direct contact with company maintenance personnel and they were informed of the nature of the malfunction. I also had a fairly strong level of certainty another crew wouldn't attempt to fly the aircraft before the malfunction was repaired; mostly because the aircraft was parked on a taxiway with its right main tire blown out. I was escorted from the aircraft to the FBO by Airport Authority Personnel. Once there; I was instructed to duty off and leave the premises by Dispatch. I didn't have any other contact with the aircraft after that. I made attempts to call my supervisors to inform them of the emergency situation. I received one email several hours later. If crews at my company had a series of clearly defined steps to follow in aftermath of an emergency; this oversight could have been prevented. In all of the confusion and rush following the event; I simply forgot to note the malfunction in the aircraft log; and no one in my company; including maintenance; noticed this until 6 days later.
